Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550280, here are decompositions:

  • 13 + 550267 = 550280
  • 67 + 550213 = 550280
  • 103 + 550177 = 550280
  • 151 + 550129 = 550280
  • 163 + 550117 = 550280
  • 271 + 550009 = 550280
  • 331 + 549949 = 550280
  • 337 + 549943 = 550280

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 550,280 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 550280 first appears in π at position 285,039 of the decimal expansion (the 285,039ordinal-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.
