Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551188, here are decompositions:

  • 59 + 551129 = 551188
  • 89 + 551099 = 551188
  • 149 + 551039 = 551188
  • 191 + 550997 = 551188
  • 227 + 550961 = 551188
  • 251 + 550937 = 551188
  • 347 + 550841 = 551188
  • 431 + 550757 = 551188

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 551,188 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 551188 first appears in π at position 433,429 of the decimal expansion (the 433,429ordinal-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.
