Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445244, here are decompositions:
- 11 + 31445233 = 31445244
- 13 + 31445231 = 31445244
- 23 + 31445221 = 31445244
- 41 + 31445203 = 31445244
- 43 + 31445201 = 31445244
- 71 + 31445173 = 31445244
- 107 + 31445137 = 31445244
- 137 + 31445107 = 31445244
Showing the first eight; more decompositions exist.
