Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668784, here are decompositions:
- 43 + 8668741 = 8668784
- 73 + 8668711 = 8668784
- 97 + 8668687 = 8668784
- 283 + 8668501 = 8668784
- 577 + 8668207 = 8668784
- 643 + 8668141 = 8668784
- 673 + 8668111 = 8668784
- 727 + 8668057 = 8668784
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 8,668,784 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
