Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551318, here are decompositions:

  • 7 + 551311 = 551318
  • 37 + 551281 = 551318
  • 139 + 551179 = 551318
  • 211 + 551107 = 551318
  • 349 + 550969 = 551318
  • 367 + 550951 = 551318
  • 379 + 550939 = 551318
  • 409 + 550909 = 551318

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 551,318 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 551318 first appears in π at position 30,607 of the decimal expansion (the 30,607ordinal-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.
