Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515586, here are decompositions:

  • 7 + 515579 = 515586
  • 23 + 515563 = 515586
  • 47 + 515539 = 515586
  • 67 + 515519 = 515586
  • 79 + 515507 = 515586
  • 109 + 515477 = 515586
  • 157 + 515429 = 515586
  • 229 + 515357 = 515586

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 515,586 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 515586 first appears in π at position 696,813 of the decimal expansion (the 696,813ordinal-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.
