Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495090, here are decompositions:

  • 19 + 495071 = 495090
  • 23 + 495067 = 495090
  • 47 + 495043 = 495090
  • 53 + 495037 = 495090
  • 73 + 495017 = 495090
  • 103 + 494987 = 495090
  • 131 + 494959 = 495090
  • 151 + 494939 = 495090

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 495,090 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 495090 first appears in π at position 209,068 of the decimal expansion (the 209,068ordinal-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.
