Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546218, here are decompositions:
- 19 + 31546199 = 31546218
- 31 + 31546187 = 31546218
- 37 + 31546181 = 31546218
- 59 + 31546159 = 31546218
- 89 + 31546129 = 31546218
- 107 + 31546111 = 31546218
- 149 + 31546069 = 31546218
- 199 + 31546019 = 31546218
Showing the first eight; more decompositions exist.
