Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023564, here are decompositions:

  • 7 + 1023557 = 1023564
  • 13 + 1023551 = 1023564
  • 23 + 1023541 = 1023564
  • 43 + 1023521 = 1023564
  • 97 + 1023467 = 1023564
  • 103 + 1023461 = 1023564
  • 151 + 1023413 = 1023564
  • 173 + 1023391 = 1023564

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 3564 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3564-02-01 (DMMYYYY (Euro, single-digit day))
  • 3564-10-02 (MMDYYYY (US, single-digit day))
  • 3564-02-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,023,564 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1023564 first appears in π at position 17,010 of the decimal expansion (the 17,010ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
