Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516518, here are decompositions:

  • 19 + 516499 = 516518
  • 61 + 516457 = 516518
  • 97 + 516421 = 516518
  • 127 + 516391 = 516518
  • 157 + 516361 = 516518
  • 199 + 516319 = 516518
  • 241 + 516277 = 516518
  • 271 + 516247 = 516518

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 516,518 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 516518 first appears in π at position 821,769 of the decimal expansion (the 821,769ordinal-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.
