Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977280, here are decompositions:

  • 11 + 977269 = 977280
  • 23 + 977257 = 977280
  • 37 + 977243 = 977280
  • 41 + 977239 = 977280
  • 47 + 977233 = 977280
  • 71 + 977209 = 977280
  • 89 + 977191 = 977280
  • 97 + 977183 = 977280

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 977,280 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 977280 first appears in π at position 798,325 of the decimal expansion (the 798,325ordinal-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.
