Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513718, here are decompositions:

  • 239 + 513479 = 513718
  • 311 + 513407 = 513718
  • 347 + 513371 = 513718
  • 449 + 513269 = 513718
  • 461 + 513257 = 513718
  • 479 + 513239 = 513718
  • 587 + 513131 = 513718
  • 617 + 513101 = 513718

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 513,718 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 513718 first appears in π at position 199,196 of the decimal expansion (the 199,196ordinal-suffix:th 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.
