Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661184, here are decompositions:

  • 3 + 8661181 = 8661184
  • 11 + 8661173 = 8661184
  • 23 + 8661161 = 8661184
  • 47 + 8661137 = 8661184
  • 137 + 8661047 = 8661184
  • 197 + 8660987 = 8661184
  • 251 + 8660933 = 8661184
  • 263 + 8660921 = 8661184

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 8,661,184 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 8661184 first appears in π at position 488,794 of the decimal expansion (the 488,794ordinal-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.
