Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515316, here are decompositions:

  • 5 + 515311 = 515316
  • 23 + 515293 = 515316
  • 37 + 515279 = 515316
  • 79 + 515237 = 515316
  • 83 + 515233 = 515316
  • 89 + 515227 = 515316
  • 163 + 515153 = 515316
  • 167 + 515149 = 515316

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 515,316 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 515316 first appears in π at position 585,028 of the decimal expansion (the 585,028ordinal-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.
