Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704220, here are decompositions:
- 37 + 8704183 = 8704220
- 61 + 8704159 = 8704220
- 97 + 8704123 = 8704220
- 103 + 8704117 = 8704220
- 193 + 8704027 = 8704220
- 277 + 8703943 = 8704220
- 331 + 8703889 = 8704220
- 367 + 8703853 = 8704220
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 8,704,220 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
