Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639190, here are decompositions:

  • 13 + 8639177 = 8639190
  • 19 + 8639171 = 8639190
  • 29 + 8639161 = 8639190
  • 37 + 8639153 = 8639190
  • 41 + 8639149 = 8639190
  • 47 + 8639143 = 8639190
  • 59 + 8639131 = 8639190
  • 67 + 8639123 = 8639190

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 8,639,190 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 8639190 first appears in π at position 155,365 of the decimal expansion (the 155,365ordinal-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.
