Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551382, here are decompositions:

  • 19 + 551363 = 551382
  • 43 + 551339 = 551382
  • 61 + 551321 = 551382
  • 71 + 551311 = 551382
  • 101 + 551281 = 551382
  • 113 + 551269 = 551382
  • 149 + 551233 = 551382
  • 151 + 551231 = 551382

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 551,382 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 551382 first appears in π at position 245,934 of the decimal expansion (the 245,934ordinal-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.
