Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454966, here are decompositions:
- 13 + 31454953 = 31454966
- 43 + 31454923 = 31454966
- 139 + 31454827 = 31454966
- 157 + 31454809 = 31454966
- 229 + 31454737 = 31454966
- 313 + 31454653 = 31454966
- 379 + 31454587 = 31454966
- 577 + 31454389 = 31454966
Showing the first eight; more decompositions exist.
