Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512726, here are decompositions:

  • 13 + 512713 = 512726
  • 43 + 512683 = 512726
  • 157 + 512569 = 512726
  • 223 + 512503 = 512726
  • 229 + 512497 = 512726
  • 283 + 512443 = 512726
  • 307 + 512419 = 512726
  • 337 + 512389 = 512726

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 512,726 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 512726 first appears in π at position 139,474 of the decimal expansion (the 139,474ordinal-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.
