Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511982, here are decompositions:

  • 19 + 511963 = 511982
  • 43 + 511939 = 511982
  • 73 + 511909 = 511982
  • 109 + 511873 = 511982
  • 139 + 511843 = 511982
  • 151 + 511831 = 511982
  • 181 + 511801 = 511982
  • 271 + 511711 = 511982

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 511,982 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 511982 first appears in π at position 856,502 of the decimal expansion (the 856,502ordinal-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.
