Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512112, here are decompositions:
- 3 + 31512109 = 31512112
- 29 + 31512083 = 31512112
- 41 + 31512071 = 31512112
- 53 + 31512059 = 31512112
- 89 + 31512023 = 31512112
- 101 + 31512011 = 31512112
- 131 + 31511981 = 31512112
- 173 + 31511939 = 31512112
Showing the first eight; more decompositions exist.
