Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518244, here are decompositions:

  • 5 + 518239 = 518244
  • 7 + 518237 = 518244
  • 11 + 518233 = 518244
  • 37 + 518207 = 518244
  • 53 + 518191 = 518244
  • 73 + 518171 = 518244
  • 107 + 518137 = 518244
  • 113 + 518131 = 518244

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 518,244 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 518244 first appears in π at position 540,301 of the decimal expansion (the 540,301ordinal-suffix:st 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.
