Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667172, here are decompositions:
- 5 + 8667167 = 8667172
- 179 + 8666993 = 8667172
- 233 + 8666939 = 8667172
- 281 + 8666891 = 8667172
- 389 + 8666783 = 8667172
- 461 + 8666711 = 8667172
- 491 + 8666681 = 8667172
- 653 + 8666519 = 8667172
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 8,667,172 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
