Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495520, here are decompositions:

  • 29 + 495491 = 495520
  • 59 + 495461 = 495520
  • 71 + 495449 = 495520
  • 83 + 495437 = 495520
  • 107 + 495413 = 495520
  • 131 + 495389 = 495520
  • 149 + 495371 = 495520
  • 173 + 495347 = 495520

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 495,520 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 495520 first appears in π at position 537,675 of the decimal expansion (the 537,675ordinal-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.
