Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551784, here are decompositions:

  • 11 + 551773 = 551784
  • 17 + 551767 = 551784
  • 31 + 551753 = 551784
  • 41 + 551743 = 551784
  • 53 + 551731 = 551784
  • 61 + 551723 = 551784
  • 67 + 551717 = 551784
  • 71 + 551713 = 551784

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 551,784 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 551784 first appears in π at position 304,900 of the decimal expansion (the 304,900ordinal-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.
