Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511124, here are decompositions:
- 13 + 31511111 = 31511124
- 53 + 31511071 = 31511124
- 67 + 31511057 = 31511124
- 83 + 31511041 = 31511124
- 131 + 31510993 = 31511124
- 167 + 31510957 = 31511124
- 191 + 31510933 = 31511124
- 193 + 31510931 = 31511124
Showing the first eight; more decompositions exist.
