Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517656, here are decompositions:

  • 17 + 517639 = 517656
  • 19 + 517637 = 517656
  • 37 + 517619 = 517656
  • 43 + 517613 = 517656
  • 47 + 517609 = 517656
  • 53 + 517603 = 517656
  • 59 + 517597 = 517656
  • 67 + 517589 = 517656

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 517,656 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 517656 first appears in π at position 4,417 of the decimal expansion (the 4,417ordinal-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.
