Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512686, here are decompositions:

  • 3 + 512683 = 512686
  • 23 + 512663 = 512686
  • 29 + 512657 = 512686
  • 89 + 512597 = 512686
  • 107 + 512579 = 512686
  • 113 + 512573 = 512686
  • 149 + 512537 = 512686
  • 179 + 512507 = 512686

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 512,686 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 512686 first appears in π at position 973,652 of the decimal expansion (the 973,652ordinal-suffix:nd 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.
