Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642200, here are decompositions:
- 3 + 8642197 = 8642200
- 11 + 8642189 = 8642200
- 41 + 8642159 = 8642200
- 53 + 8642147 = 8642200
- 59 + 8642141 = 8642200
- 89 + 8642111 = 8642200
- 101 + 8642099 = 8642200
- 137 + 8642063 = 8642200
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 8,642,200 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
