Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518972, here are decompositions:

  • 19 + 518953 = 518972
  • 61 + 518911 = 518972
  • 79 + 518893 = 518972
  • 109 + 518863 = 518972
  • 163 + 518809 = 518972
  • 193 + 518779 = 518972
  • 211 + 518761 = 518972
  • 229 + 518743 = 518972

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 518,972 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 518972 first appears in π at position 631,635 of the decimal expansion (the 631,635ordinal-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.
