Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628212, here are decompositions:

  • 31 + 8628181 = 8628212
  • 163 + 8628049 = 8628212
  • 181 + 8628031 = 8628212
  • 193 + 8628019 = 8628212
  • 379 + 8627833 = 8628212
  • 499 + 8627713 = 8628212
  • 601 + 8627611 = 8628212
  • 631 + 8627581 = 8628212

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 8,628,212 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 8628212 first appears in π at position 652,403 of the decimal expansion (the 652,403ordinal-suffix:rd 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.
