Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667772, here are decompositions:
- 83 + 8667689 = 8667772
- 131 + 8667641 = 8667772
- 233 + 8667539 = 8667772
- 251 + 8667521 = 8667772
- 353 + 8667419 = 8667772
- 359 + 8667413 = 8667772
- 401 + 8667371 = 8667772
- 593 + 8667179 = 8667772
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 8,667,772 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
