Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986180, here are decompositions:

  • 3 + 986177 = 986180
  • 31 + 986149 = 986180
  • 37 + 986143 = 986180
  • 43 + 986137 = 986180
  • 67 + 986113 = 986180
  • 79 + 986101 = 986180
  • 109 + 986071 = 986180
  • 127 + 986053 = 986180

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 986,180 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 986180 first appears in π at position 888,718 of the decimal expansion (the 888,718ordinal-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.
