Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986866, here are decompositions:

  • 17 + 986849 = 986866
  • 29 + 986837 = 986866
  • 47 + 986819 = 986866
  • 53 + 986813 = 986866
  • 107 + 986759 = 986866
  • 137 + 986729 = 986866
  • 149 + 986717 = 986866
  • 173 + 986693 = 986866

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 986,866 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 986866 first appears in π at position 473,983 of the decimal expansion (the 473,983ordinal-suffix:rd 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.
