Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715240, here are decompositions:
- 7 + 8715233 = 8715240
- 31 + 8715209 = 8715240
- 47 + 8715193 = 8715240
- 59 + 8715181 = 8715240
- 89 + 8715151 = 8715240
- 97 + 8715143 = 8715240
- 137 + 8715103 = 8715240
- 181 + 8715059 = 8715240
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 8,715,240 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
