Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716240, here are decompositions:
- 3 + 8716237 = 8716240
- 23 + 8716217 = 8716240
- 53 + 8716187 = 8716240
- 59 + 8716181 = 8716240
- 89 + 8716151 = 8716240
- 131 + 8716109 = 8716240
- 179 + 8716061 = 8716240
- 227 + 8716013 = 8716240
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 8,716,240 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
