Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545486, here are decompositions:
- 17 + 31545469 = 31545486
- 47 + 31545439 = 31545486
- 79 + 31545407 = 31545486
- 107 + 31545379 = 31545486
- 113 + 31545373 = 31545486
- 157 + 31545329 = 31545486
- 163 + 31545323 = 31545486
- 199 + 31545287 = 31545486
Showing the first eight; more decompositions exist.
