Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548960, here are decompositions:
- 7 + 31548953 = 31548960
- 89 + 31548871 = 31548960
- 103 + 31548857 = 31548960
- 137 + 31548823 = 31548960
- 193 + 31548767 = 31548960
- 197 + 31548763 = 31548960
- 211 + 31548749 = 31548960
- 227 + 31548733 = 31548960
Showing the first eight; more decompositions exist.
