Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986178, here are decompositions:

  • 29 + 986149 = 986178
  • 31 + 986147 = 986178
  • 41 + 986137 = 986178
  • 47 + 986131 = 986178
  • 107 + 986071 = 986178
  • 131 + 986047 = 986178
  • 181 + 985997 = 986178
  • 197 + 985981 = 986178

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 986,178 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 986178 first appears in π at position 186,858 of the decimal expansion (the 186,858ordinal-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.
