Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512812, here are decompositions:

  • 71 + 512741 = 512812
  • 101 + 512711 = 512812
  • 149 + 512663 = 512812
  • 191 + 512621 = 512812
  • 233 + 512579 = 512812
  • 239 + 512573 = 512812
  • 269 + 512543 = 512812
  • 281 + 512531 = 512812

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 512,812 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 512812 first appears in π at position 205,354 of the decimal expansion (the 205,354ordinal-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.
