Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543022, here are decompositions:
- 3 + 31543019 = 31543022
- 13 + 31543009 = 31543022
- 31 + 31542991 = 31543022
- 73 + 31542949 = 31543022
- 79 + 31542943 = 31543022
- 193 + 31542829 = 31543022
- 211 + 31542811 = 31543022
- 223 + 31542799 = 31543022
Showing the first eight; more decompositions exist.
