Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515946, here are decompositions:

  • 5 + 515941 = 515946
  • 17 + 515929 = 515946
  • 23 + 515923 = 515946
  • 29 + 515917 = 515946
  • 59 + 515887 = 515946
  • 73 + 515873 = 515946
  • 89 + 515857 = 515946
  • 103 + 515843 = 515946

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 515,946 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 515946 first appears in π at position 513,795 of the decimal expansion (the 513,795ordinal-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.
