Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672904, here are decompositions:
- 7 + 8672897 = 8672904
- 13 + 8672891 = 8672904
- 43 + 8672861 = 8672904
- 73 + 8672831 = 8672904
- 83 + 8672821 = 8672904
- 103 + 8672801 = 8672904
- 113 + 8672791 = 8672904
- 131 + 8672773 = 8672904
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 8,672,904 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
