Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670664, here are decompositions:
- 11 + 8670653 = 8670664
- 53 + 8670611 = 8670664
- 113 + 8670551 = 8670664
- 131 + 8670533 = 8670664
- 173 + 8670491 = 8670664
- 257 + 8670407 = 8670664
- 293 + 8670371 = 8670664
- 311 + 8670353 = 8670664
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 8,670,664 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
