Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518814, here are decompositions:

  • 5 + 518809 = 518814
  • 7 + 518807 = 518814
  • 11 + 518803 = 518814
  • 13 + 518801 = 518814
  • 47 + 518767 = 518814
  • 53 + 518761 = 518814
  • 67 + 518747 = 518814
  • 71 + 518743 = 518814

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 518,814 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 518814 first appears in π at position 208,866 of the decimal expansion (the 208,866ordinal-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.
