Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535262, here are decompositions:
- 29 + 31535233 = 31535262
- 43 + 31535219 = 31535262
- 79 + 31535183 = 31535262
- 89 + 31535173 = 31535262
- 131 + 31535131 = 31535262
- 139 + 31535123 = 31535262
- 149 + 31535113 = 31535262
- 179 + 31535083 = 31535262
Showing the first eight; more decompositions exist.
