Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624512, here are decompositions:
- 5 + 8624507 = 8624512
- 53 + 8624459 = 8624512
- 263 + 8624249 = 8624512
- 269 + 8624243 = 8624512
- 311 + 8624201 = 8624512
- 353 + 8624159 = 8624512
- 359 + 8624153 = 8624512
- 383 + 8624129 = 8624512
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 8,624,512 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
