Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670172, here are decompositions:
- 83 + 8670089 = 8670172
- 101 + 8670071 = 8670172
- 131 + 8670041 = 8670172
- 179 + 8669993 = 8670172
- 191 + 8669981 = 8670172
- 233 + 8669939 = 8670172
- 293 + 8669879 = 8670172
- 311 + 8669861 = 8670172
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 8,670,172 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
