Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673220, here are decompositions:
- 11 + 8673209 = 8673220
- 53 + 8673167 = 8673220
- 89 + 8673131 = 8673220
- 107 + 8673113 = 8673220
- 113 + 8673107 = 8673220
- 191 + 8673029 = 8673220
- 251 + 8672969 = 8673220
- 293 + 8672927 = 8673220
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 8,673,220 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
