Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555240, here are decompositions:

  • 19 + 555221 = 555240
  • 31 + 555209 = 555240
  • 73 + 555167 = 555240
  • 97 + 555143 = 555240
  • 131 + 555109 = 555240
  • 149 + 555091 = 555240
  • 157 + 555083 = 555240
  • 163 + 555077 = 555240

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 555,240 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 555240 first appears in π at position 500,719 of the decimal expansion (the 500,719ordinal-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.
