Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548732, here are decompositions:
- 73 + 31548659 = 31548732
- 79 + 31548653 = 31548732
- 113 + 31548619 = 31548732
- 139 + 31548593 = 31548732
- 181 + 31548551 = 31548732
- 199 + 31548533 = 31548732
- 211 + 31548521 = 31548732
- 233 + 31548499 = 31548732
Showing the first eight; more decompositions exist.
