Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512442, here are decompositions:

  • 13 + 512429 = 512442
  • 23 + 512419 = 512442
  • 53 + 512389 = 512442
  • 89 + 512353 = 512442
  • 109 + 512333 = 512442
  • 131 + 512311 = 512442
  • 173 + 512269 = 512442
  • 191 + 512251 = 512442

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 512,442 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 512442 first appears in π at position 715,872 of the decimal expansion (the 715,872ordinal-suffix:nd 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.
