Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019432, here are decompositions:

  • 19 + 1019413 = 1019432
  • 79 + 1019353 = 1019432
  • 103 + 1019329 = 1019432
  • 151 + 1019281 = 1019432
  • 181 + 1019251 = 1019432
  • 223 + 1019209 = 1019432
  • 313 + 1019119 = 1019432
  • 373 + 1019059 = 1019432

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 9432 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 9432-10-01 (MMDYYYY (US, single-digit day))
  • 9432-01-10 (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 1,019,432 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 1019432 first appears in π at position 470,316 of the decimal expansion (the 470,316ordinal-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.
