Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664212, here are decompositions:
- 19 + 8664193 = 8664212
- 31 + 8664181 = 8664212
- 103 + 8664109 = 8664212
- 313 + 8663899 = 8664212
- 409 + 8663803 = 8664212
- 619 + 8663593 = 8664212
- 691 + 8663521 = 8664212
- 709 + 8663503 = 8664212
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 8,664,212 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
