Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450966, here are decompositions:
- 5 + 31450961 = 31450966
- 17 + 31450949 = 31450966
- 137 + 31450829 = 31450966
- 179 + 31450787 = 31450966
- 227 + 31450739 = 31450966
- 347 + 31450619 = 31450966
- 353 + 31450613 = 31450966
- 383 + 31450583 = 31450966
Showing the first eight; more decompositions exist.
