Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555180, here are decompositions:

  • 13 + 555167 = 555180
  • 37 + 555143 = 555180
  • 61 + 555119 = 555180
  • 71 + 555109 = 555180
  • 83 + 555097 = 555180
  • 89 + 555091 = 555180
  • 97 + 555083 = 555180
  • 103 + 555077 = 555180

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 555,180 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 555180 first appears in π at position 531,023 of the decimal expansion (the 531,023ordinal-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.
