Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495620, here are decompositions:

  • 3 + 495617 = 495620
  • 7 + 495613 = 495620
  • 31 + 495589 = 495620
  • 61 + 495559 = 495620
  • 109 + 495511 = 495620
  • 163 + 495457 = 495620
  • 199 + 495421 = 495620
  • 277 + 495343 = 495620

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 495,620 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 495620 first appears in π at position 128,373 of the decimal expansion (the 128,373ordinal-suffix:rd 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.
