Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717040, here are decompositions:
- 19 + 8717021 = 8717040
- 29 + 8717011 = 8717040
- 41 + 8716999 = 8717040
- 43 + 8716997 = 8717040
- 83 + 8716957 = 8717040
- 97 + 8716943 = 8717040
- 149 + 8716891 = 8717040
- 151 + 8716889 = 8717040
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 8,717,040 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
