Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628400, here are decompositions:
- 17 + 8628383 = 8628400
- 23 + 8628377 = 8628400
- 41 + 8628359 = 8628400
- 47 + 8628353 = 8628400
- 107 + 8628293 = 8628400
- 167 + 8628233 = 8628400
- 197 + 8628203 = 8628400
- 227 + 8628173 = 8628400
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 8,628,400 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
