Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495258, here are decompositions:

  • 17 + 495241 = 495258
  • 37 + 495221 = 495258
  • 47 + 495211 = 495258
  • 59 + 495199 = 495258
  • 97 + 495161 = 495258
  • 107 + 495151 = 495258
  • 109 + 495149 = 495258
  • 139 + 495119 = 495258

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 495,258 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 495258 first appears in π at position 221,145 of the decimal expansion (the 221,145ordinal-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.
