Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534212, here are decompositions:
- 13 + 31534199 = 31534212
- 29 + 31534183 = 31534212
- 43 + 31534169 = 31534212
- 71 + 31534141 = 31534212
- 109 + 31534103 = 31534212
- 139 + 31534073 = 31534212
- 179 + 31534033 = 31534212
- 233 + 31533979 = 31534212
Showing the first eight; more decompositions exist.
