Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667748, here are decompositions:
- 41 + 8667707 = 8667748
- 59 + 8667689 = 8667748
- 71 + 8667677 = 8667748
- 107 + 8667641 = 8667748
- 137 + 8667611 = 8667748
- 227 + 8667521 = 8667748
- 251 + 8667497 = 8667748
- 317 + 8667431 = 8667748
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 8,667,748 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
