Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534250, here are decompositions:
- 3 + 31534247 = 31534250
- 19 + 31534231 = 31534250
- 67 + 31534183 = 31534250
- 109 + 31534141 = 31534250
- 193 + 31534057 = 31534250
- 199 + 31534051 = 31534250
- 271 + 31533979 = 31534250
- 283 + 31533967 = 31534250
Showing the first eight; more decompositions exist.
