Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104664, here are decompositions:
- 5 + 104659 = 104664
- 13 + 104651 = 104664
- 41 + 104623 = 104664
- 67 + 104597 = 104664
- 71 + 104593 = 104664
- 103 + 104561 = 104664
- 113 + 104551 = 104664
- 127 + 104537 = 104664
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 104,664 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
