Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624100, here are decompositions:
- 41 + 8624059 = 8624100
- 73 + 8624027 = 8624100
- 83 + 8624017 = 8624100
- 97 + 8624003 = 8624100
- 131 + 8623969 = 8624100
- 137 + 8623963 = 8624100
- 139 + 8623961 = 8624100
- 197 + 8623903 = 8624100
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 8,624,100 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
