Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515700, here are decompositions:

  • 7 + 515693 = 515700
  • 13 + 515687 = 515700
  • 19 + 515681 = 515700
  • 23 + 515677 = 515700
  • 37 + 515663 = 515700
  • 47 + 515653 = 515700
  • 61 + 515639 = 515700
  • 79 + 515621 = 515700

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 515,700 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 515700 first appears in π at position 459,061 of the decimal expansion (the 459,061ordinal-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.
