Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551626, here are decompositions:

  • 29 + 551597 = 551626
  • 83 + 551543 = 551626
  • 107 + 551519 = 551626
  • 137 + 551489 = 551626
  • 239 + 551387 = 551626
  • 263 + 551363 = 551626
  • 419 + 551207 = 551626
  • 557 + 551069 = 551626

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 551,626 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 551626 first appears in π at position 120,140 of the decimal expansion (the 120,140ordinal-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.
