Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509166, here are decompositions:

  • 17 + 509149 = 509166
  • 19 + 509147 = 509166
  • 29 + 509137 = 509166
  • 43 + 509123 = 509166
  • 79 + 509087 = 509166
  • 103 + 509063 = 509166
  • 113 + 509053 = 509166
  • 139 + 509027 = 509166

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 509,166 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 509166 first appears in π at position 578,102 of the decimal expansion (the 578,102ordinal-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.
