Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543268, here are decompositions:
- 37 + 31543231 = 31543268
- 61 + 31543207 = 31543268
- 199 + 31543069 = 31543268
- 277 + 31542991 = 31543268
- 331 + 31542937 = 31543268
- 439 + 31542829 = 31543268
- 457 + 31542811 = 31543268
- 541 + 31542727 = 31543268
Showing the first eight; more decompositions exist.
