Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543148, here are decompositions:
- 79 + 31543069 = 31543148
- 139 + 31543009 = 31543148
- 157 + 31542991 = 31543148
- 181 + 31542967 = 31543148
- 199 + 31542949 = 31543148
- 211 + 31542937 = 31543148
- 271 + 31542877 = 31543148
- 337 + 31542811 = 31543148
Showing the first eight; more decompositions exist.
