Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708400, here are decompositions:
- 7 + 8708393 = 8708400
- 13 + 8708387 = 8708400
- 61 + 8708339 = 8708400
- 109 + 8708291 = 8708400
- 131 + 8708269 = 8708400
- 139 + 8708261 = 8708400
- 199 + 8708201 = 8708400
- 227 + 8708173 = 8708400
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 8,708,400 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
