Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534254, here are decompositions:
- 7 + 31534247 = 31534254
- 13 + 31534241 = 31534254
- 23 + 31534231 = 31534254
- 67 + 31534187 = 31534254
- 71 + 31534183 = 31534254
- 113 + 31534141 = 31534254
- 137 + 31534117 = 31534254
- 151 + 31534103 = 31534254
Showing the first eight; more decompositions exist.
