Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623222, here are decompositions:

  • 29 + 8623193 = 8623222
  • 149 + 8623073 = 8623222
  • 191 + 8623031 = 8623222
  • 239 + 8622983 = 8623222
  • 263 + 8622959 = 8623222
  • 659 + 8622563 = 8623222
  • 701 + 8622521 = 8623222
  • 761 + 8622461 = 8623222

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 8,623,222 and was likely granted around 2013.

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

Position in π

The digit sequence 8623222 first appears in π at position 710,191 of the decimal expansion (the 710,191ordinal-suffix:st 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.
