Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642184, here are decompositions:

  • 11 + 8642173 = 8642184
  • 37 + 8642147 = 8642184
  • 43 + 8642141 = 8642184
  • 73 + 8642111 = 8642184
  • 107 + 8642077 = 8642184
  • 127 + 8642057 = 8642184
  • 151 + 8642033 = 8642184
  • 157 + 8642027 = 8642184

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 8,642,184 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 8642184 first appears in π at position 250,882 of the decimal expansion (the 250,882ordinal-suffix:nd 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.
