Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551898, here are decompositions:

  • 37 + 551861 = 551898
  • 89 + 551809 = 551898
  • 97 + 551801 = 551898
  • 131 + 551767 = 551898
  • 167 + 551731 = 551898
  • 181 + 551717 = 551898
  • 227 + 551671 = 551898
  • 239 + 551659 = 551898

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 551,898 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 551898 first appears in π at position 81,314 of the decimal expansion (the 81,314ordinal-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.
