Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513512, here are decompositions:

  • 3 + 513509 = 513512
  • 31 + 513481 = 513512
  • 73 + 513439 = 513512
  • 193 + 513319 = 513512
  • 199 + 513313 = 513512
  • 229 + 513283 = 513512
  • 409 + 513103 = 513512
  • 499 + 513013 = 513512

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 513,512 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 513512 first appears in π at position 181,345 of the decimal expansion (the 181,345ordinal-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.
