Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621004, here are decompositions:
- 11 + 8620993 = 8621004
- 31 + 8620973 = 8621004
- 53 + 8620951 = 8621004
- 61 + 8620943 = 8621004
- 107 + 8620897 = 8621004
- 131 + 8620873 = 8621004
- 157 + 8620847 = 8621004
- 163 + 8620841 = 8621004
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 8,621,004 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
