Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748740, here are decompositions:
- 31 + 8748709 = 8748740
- 67 + 8748673 = 8748740
- 97 + 8748643 = 8748740
- 139 + 8748601 = 8748740
- 151 + 8748589 = 8748740
- 157 + 8748583 = 8748740
- 241 + 8748499 = 8748740
- 271 + 8748469 = 8748740
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 8,748,740 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
