Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664678, here are decompositions:
- 7 + 8664671 = 8664678
- 17 + 8664661 = 8664678
- 97 + 8664581 = 8664678
- 131 + 8664547 = 8664678
- 149 + 8664529 = 8664678
- 151 + 8664527 = 8664678
- 227 + 8664451 = 8664678
- 251 + 8664427 = 8664678
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.132.54.102.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,664,678 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
