Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013640, here are decompositions:

  • 11 + 1013629 = 1013640
  • 13 + 1013627 = 1013640
  • 31 + 1013609 = 1013640
  • 37 + 1013603 = 1013640
  • 59 + 1013581 = 1013640
  • 71 + 1013569 = 1013640
  • 107 + 1013533 = 1013640
  • 109 + 1013531 = 1013640

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 3640 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3640-10-01 (MMDYYYY (US, single-digit day))
  • 3640-01-10 (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 1,013,640 and was likely granted around 1911.

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

Position in π

The digit sequence 1013640 first appears in π at position 333,667 of the decimal expansion (the 333,667ordinal-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.
