Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551404, here are decompositions:

  • 17 + 551387 = 551404
  • 23 + 551381 = 551404
  • 41 + 551363 = 551404
  • 83 + 551321 = 551404
  • 107 + 551297 = 551404
  • 173 + 551231 = 551404
  • 197 + 551207 = 551404
  • 311 + 551093 = 551404

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 551,404 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 551404 first appears in π at position 675,667 of the decimal expansion (the 675,667ordinal-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.
