Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667784, here are decompositions:
- 107 + 8667677 = 8667784
- 131 + 8667653 = 8667784
- 173 + 8667611 = 8667784
- 263 + 8667521 = 8667784
- 353 + 8667431 = 8667784
- 557 + 8667227 = 8667784
- 617 + 8667167 = 8667784
- 647 + 8667137 = 8667784
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 8,667,784 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
