Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556180, here are decompositions:

  • 3 + 556177 = 556180
  • 113 + 556067 = 556180
  • 137 + 556043 = 556180
  • 173 + 556007 = 556180
  • 227 + 555953 = 556180
  • 239 + 555941 = 556180
  • 353 + 555827 = 556180
  • 419 + 555761 = 556180

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 556,180 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 556180 first appears in π at position 691,208 of the decimal expansion (the 691,208ordinal-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.
