Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551042, here are decompositions:

  • 3 + 551039 = 551042
  • 73 + 550969 = 551042
  • 103 + 550939 = 551042
  • 139 + 550903 = 551042
  • 181 + 550861 = 551042
  • 199 + 550843 = 551042
  • 211 + 550831 = 551042
  • 229 + 550813 = 551042

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 551,042 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 551042 first appears in π at position 122,734 of the decimal expansion (the 122,734ordinal-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.
