Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673172, here are decompositions:
- 5 + 8673167 = 8673172
- 41 + 8673131 = 8673172
- 59 + 8673113 = 8673172
- 239 + 8672933 = 8673172
- 281 + 8672891 = 8673172
- 311 + 8672861 = 8673172
- 353 + 8672819 = 8673172
- 383 + 8672789 = 8673172
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 8,673,172 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
