Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684142, here are decompositions:
- 11 + 8684131 = 8684142
- 31 + 8684111 = 8684142
- 43 + 8684099 = 8684142
- 53 + 8684089 = 8684142
- 73 + 8684069 = 8684142
- 113 + 8684029 = 8684142
- 139 + 8684003 = 8684142
- 199 + 8683943 = 8684142
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 8,684,142 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
