Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672172, here are decompositions:
- 11 + 8672161 = 8672172
- 71 + 8672101 = 8672172
- 73 + 8672099 = 8672172
- 109 + 8672063 = 8672172
- 181 + 8671991 = 8672172
- 191 + 8671981 = 8672172
- 193 + 8671979 = 8672172
- 433 + 8671739 = 8672172
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 8,672,172 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
