Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988986, here are decompositions:

  • 7 + 988979 = 988986
  • 23 + 988963 = 988986
  • 109 + 988877 = 988986
  • 127 + 988859 = 988986
  • 137 + 988849 = 988986
  • 149 + 988837 = 988986
  • 157 + 988829 = 988986
  • 197 + 988789 = 988986

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 988,986 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 988986 first appears in π at position 128,935 of the decimal expansion (the 128,935ordinal-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.
