Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677772, here are decompositions:
- 13 + 8677759 = 8677772
- 109 + 8677663 = 8677772
- 373 + 8677399 = 8677772
- 379 + 8677393 = 8677772
- 601 + 8677171 = 8677772
- 823 + 8676949 = 8677772
- 991 + 8676781 = 8677772
- 1021 + 8676751 = 8677772
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 8,677,772 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
