Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495872, here are decompositions:

  • 43 + 495829 = 495872
  • 73 + 495799 = 495872
  • 103 + 495769 = 495872
  • 193 + 495679 = 495872
  • 283 + 495589 = 495872
  • 313 + 495559 = 495872
  • 439 + 495433 = 495872
  • 571 + 495301 = 495872

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 495,872 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 495872 first appears in π at position 36,988 of the decimal expansion (the 36,988ordinal-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.
