Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622240, here are decompositions:
- 17 + 8622223 = 8622240
- 31 + 8622209 = 8622240
- 103 + 8622137 = 8622240
- 113 + 8622127 = 8622240
- 127 + 8622113 = 8622240
- 199 + 8622041 = 8622240
- 223 + 8622017 = 8622240
- 229 + 8622011 = 8622240
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,622,240 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
