Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516216, here are decompositions:

  • 7 + 516209 = 516216
  • 17 + 516199 = 516216
  • 23 + 516193 = 516216
  • 37 + 516179 = 516216
  • 47 + 516169 = 516216
  • 53 + 516163 = 516216
  • 59 + 516157 = 516216
  • 89 + 516127 = 516216

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 516,216 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 516216 first appears in π at position 363,173 of the decimal expansion (the 363,173ordinal-suffix:rd 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.
