Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512422, here are decompositions:

  • 3 + 512419 = 512422
  • 89 + 512333 = 512422
  • 101 + 512321 = 512422
  • 173 + 512249 = 512422
  • 401 + 512021 = 512422
  • 431 + 511991 = 512422
  • 461 + 511961 = 512422
  • 563 + 511859 = 512422

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 512,422 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 512422 first appears in π at position 668,387 of the decimal expansion (the 668,387ordinal-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.
