Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551384, here are decompositions:

  • 3 + 551381 = 551384
  • 37 + 551347 = 551384
  • 73 + 551311 = 551384
  • 103 + 551281 = 551384
  • 151 + 551233 = 551384
  • 241 + 551143 = 551384
  • 271 + 551113 = 551384
  • 277 + 551107 = 551384

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 551,384 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 551384 first appears in π at position 141,202 of the decimal expansion (the 141,202ordinal-suffix:nd 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.
