Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748720, here are decompositions:
- 7 + 8748713 = 8748720
- 11 + 8748709 = 8748720
- 47 + 8748673 = 8748720
- 67 + 8748653 = 8748720
- 73 + 8748647 = 8748720
- 131 + 8748589 = 8748720
- 137 + 8748583 = 8748720
- 139 + 8748581 = 8748720
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 8,748,720 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
