Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667520, here are decompositions:
- 23 + 8667497 = 8667520
- 89 + 8667431 = 8667520
- 101 + 8667419 = 8667520
- 107 + 8667413 = 8667520
- 149 + 8667371 = 8667520
- 263 + 8667257 = 8667520
- 293 + 8667227 = 8667520
- 353 + 8667167 = 8667520
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 8,667,520 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
