Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516656, here are decompositions:

  • 3 + 516653 = 516656
  • 13 + 516643 = 516656
  • 37 + 516619 = 516656
  • 67 + 516589 = 516656
  • 139 + 516517 = 516656
  • 157 + 516499 = 516656
  • 163 + 516493 = 516656
  • 199 + 516457 = 516656

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 516,656 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 516656 first appears in π at position 147,500 of the decimal expansion (the 147,500ordinal-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.
