Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516646, here are decompositions:

  • 3 + 516643 = 516646
  • 23 + 516623 = 516646
  • 29 + 516617 = 516646
  • 47 + 516599 = 516646
  • 59 + 516587 = 516646
  • 83 + 516563 = 516646
  • 107 + 516539 = 516646
  • 197 + 516449 = 516646

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 516,646 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 516646 first appears in π at position 151,734 of the decimal expansion (the 151,734ordinal-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.
