Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664478, here are decompositions:
- 5 + 8664473 = 8664478
- 47 + 8664431 = 8664478
- 59 + 8664419 = 8664478
- 89 + 8664389 = 8664478
- 101 + 8664377 = 8664478
- 149 + 8664329 = 8664478
- 167 + 8664311 = 8664478
- 491 + 8663987 = 8664478
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.132.53.158.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,664,478 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
