Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515994, here are decompositions:
- 5 + 31515989 = 31515994
- 53 + 31515941 = 31515994
- 101 + 31515893 = 31515994
- 113 + 31515881 = 31515994
- 137 + 31515857 = 31515994
- 173 + 31515821 = 31515994
- 227 + 31515767 = 31515994
- 311 + 31515683 = 31515994
Showing the first eight; more decompositions exist.
