Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556250, here are decompositions:

  • 7 + 556243 = 556250
  • 31 + 556219 = 556250
  • 73 + 556177 = 556250
  • 127 + 556123 = 556250
  • 157 + 556093 = 556250
  • 181 + 556069 = 556250
  • 199 + 556051 = 556250
  • 223 + 556027 = 556250

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 556,250 and was likely granted around 1895.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 556250 first appears in π at position 317,109 of the decimal expansion (the 317,109ordinal-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.
