Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551680, here are decompositions:

  • 29 + 551651 = 551680
  • 83 + 551597 = 551680
  • 131 + 551549 = 551680
  • 137 + 551543 = 551680
  • 191 + 551489 = 551680
  • 197 + 551483 = 551680
  • 257 + 551423 = 551680
  • 293 + 551387 = 551680

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 551,680 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 551680 first appears in π at position 618,928 of the decimal expansion (the 618,928ordinal-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.
