Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7508, here are decompositions:
- 19 + 7489 = 7508
- 31 + 7477 = 7508
- 97 + 7411 = 7508
- 139 + 7369 = 7508
- 157 + 7351 = 7508
- 199 + 7309 = 7508
- 211 + 7297 = 7508
- 271 + 7237 = 7508
Showing the first eight; more decompositions exist.
