Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666028, here are decompositions:

  • 5 + 8666023 = 8666028
  • 11 + 8666017 = 8666028
  • 29 + 8665999 = 8666028
  • 37 + 8665991 = 8666028
  • 61 + 8665967 = 8666028
  • 79 + 8665949 = 8666028
  • 89 + 8665939 = 8666028
  • 97 + 8665931 = 8666028

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 8,666,028 and was likely granted around 2014.

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

Position in π

The digit sequence 8666028 first appears in π at position 396,148 of the decimal expansion (the 396,148ordinal-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.
