Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513772, here are decompositions:

  • 3 + 513769 = 513772
  • 5 + 513767 = 513772
  • 11 + 513761 = 513772
  • 23 + 513749 = 513772
  • 41 + 513731 = 513772
  • 53 + 513719 = 513772
  • 89 + 513683 = 513772
  • 131 + 513641 = 513772

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 513,772 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 513772 first appears in π at position 510,629 of the decimal expansion (the 510,629ordinal-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.
