Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499940, here are decompositions:

  • 13 + 499927 = 499940
  • 37 + 499903 = 499940
  • 43 + 499897 = 499940
  • 61 + 499879 = 499940
  • 139 + 499801 = 499940
  • 193 + 499747 = 499940
  • 211 + 499729 = 499940
  • 223 + 499717 = 499940

Showing the first eight; more decompositions exist.

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 499,940 and was likely granted around 1893.

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

Position in π

The digit sequence 499940 first appears in π at position 299,718 of the decimal expansion (the 299,718ordinal-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.
