Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513618, here are decompositions:

  • 89 + 513529 = 513618
  • 107 + 513511 = 513618
  • 109 + 513509 = 513618
  • 137 + 513481 = 513618
  • 139 + 513479 = 513618
  • 179 + 513439 = 513618
  • 191 + 513427 = 513618
  • 199 + 513419 = 513618

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 513,618 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 513618 first appears in π at position 110,710 of the decimal expansion (the 110,710ordinal-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.
