Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516220, here are decompositions:

  • 11 + 516209 = 516220
  • 41 + 516179 = 516220
  • 59 + 516161 = 516220
  • 167 + 516053 = 516220
  • 197 + 516023 = 516220
  • 227 + 515993 = 516220
  • 251 + 515969 = 516220
  • 269 + 515951 = 516220

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 516,220 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 516220 first appears in π at position 432,052 of the decimal expansion (the 432,052ordinal-suffix:nd 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.
