Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513860, here are decompositions:

  • 19 + 513841 = 513860
  • 31 + 513829 = 513860
  • 79 + 513781 = 513860
  • 163 + 513697 = 513860
  • 181 + 513679 = 513860
  • 211 + 513649 = 513860
  • 229 + 513631 = 513860
  • 331 + 513529 = 513860

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 513,860 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 513860 first appears in π at position 229,432 of the decimal expansion (the 229,432ordinal-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.
