Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513370, here are decompositions:

  • 3 + 513367 = 513370
  • 17 + 513353 = 513370
  • 23 + 513347 = 513370
  • 29 + 513341 = 513370
  • 59 + 513311 = 513370
  • 101 + 513269 = 513370
  • 113 + 513257 = 513370
  • 131 + 513239 = 513370

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 513,370 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 513370 first appears in π at position 41,643 of the decimal expansion (the 41,643ordinal-suffix:rd 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.
