Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518344, here are decompositions:

  • 3 + 518341 = 518344
  • 17 + 518327 = 518344
  • 53 + 518291 = 518344
  • 83 + 518261 = 518344
  • 107 + 518237 = 518344
  • 137 + 518207 = 518344
  • 173 + 518171 = 518344
  • 191 + 518153 = 518344

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 518,344 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 518344 first appears in π at position 142,522 of the decimal expansion (the 142,522ordinal-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.
