Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551782, here are decompositions:

  • 29 + 551753 = 551782
  • 53 + 551729 = 551782
  • 59 + 551723 = 551782
  • 89 + 551693 = 551782
  • 131 + 551651 = 551782
  • 233 + 551549 = 551782
  • 239 + 551543 = 551782
  • 263 + 551519 = 551782

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 551,782 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 551782 first appears in π at position 19,996 of the decimal expansion (the 19,996ordinal-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.
