Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645004, here are decompositions:
- 13 + 8644991 = 8645004
- 41 + 8644963 = 8645004
- 47 + 8644957 = 8645004
- 101 + 8644903 = 8645004
- 131 + 8644873 = 8645004
- 223 + 8644781 = 8645004
- 233 + 8644771 = 8645004
- 281 + 8644723 = 8645004
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 8,645,004 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
