Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642022, here are decompositions:
- 19 + 8642003 = 8642022
- 31 + 8641991 = 8642022
- 73 + 8641949 = 8642022
- 113 + 8641909 = 8642022
- 131 + 8641891 = 8642022
- 139 + 8641883 = 8642022
- 149 + 8641873 = 8642022
- 239 + 8641783 = 8642022
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 8,642,022 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
