Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551828, here are decompositions:

  • 19 + 551809 = 551828
  • 61 + 551767 = 551828
  • 97 + 551731 = 551828
  • 139 + 551689 = 551828
  • 157 + 551671 = 551828
  • 241 + 551587 = 551828
  • 271 + 551557 = 551828
  • 367 + 551461 = 551828

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 551,828 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 551828 first appears in π at position 714,779 of the decimal expansion (the 714,779ordinal-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.
