Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512070, here are decompositions:
- 11 + 31512059 = 31512070
- 47 + 31512023 = 31512070
- 53 + 31512017 = 31512070
- 59 + 31512011 = 31512070
- 89 + 31511981 = 31512070
- 101 + 31511969 = 31512070
- 131 + 31511939 = 31512070
- 137 + 31511933 = 31512070
Showing the first eight; more decompositions exist.
