Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512082, here are decompositions:
- 11 + 31512071 = 31512082
- 23 + 31512059 = 31512082
- 59 + 31512023 = 31512082
- 71 + 31512011 = 31512082
- 89 + 31511993 = 31512082
- 101 + 31511981 = 31512082
- 113 + 31511969 = 31512082
- 149 + 31511933 = 31512082
Showing the first eight; more decompositions exist.
