Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624000, here are decompositions:
- 31 + 8623969 = 8624000
- 37 + 8623963 = 8624000
- 61 + 8623939 = 8624000
- 97 + 8623903 = 8624000
- 103 + 8623897 = 8624000
- 157 + 8623843 = 8624000
- 193 + 8623807 = 8624000
- 199 + 8623801 = 8624000
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 8,624,000 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
