Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987080, here are decompositions:

  • 13 + 987067 = 987080
  • 19 + 987061 = 987080
  • 37 + 987043 = 987080
  • 67 + 987013 = 987080
  • 97 + 986983 = 987080
  • 139 + 986941 = 987080
  • 151 + 986929 = 987080
  • 223 + 986857 = 987080

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 987,080 and was likely granted around 1911.

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

Position in π

The digit sequence 987080 first appears in π at position 334,180 of the decimal expansion (the 334,180ordinal-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.
