Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551902, here are decompositions:

  • 41 + 551861 = 551902
  • 53 + 551849 = 551902
  • 59 + 551843 = 551902
  • 89 + 551813 = 551902
  • 101 + 551801 = 551902
  • 149 + 551753 = 551902
  • 173 + 551729 = 551902
  • 179 + 551723 = 551902

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 551,902 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 551902 first appears in π at position 188,732 of the decimal expansion (the 188,732ordinal-suffix:nd 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.
