Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543832, here are decompositions:
- 3 + 31543829 = 31543832
- 109 + 31543723 = 31543832
- 163 + 31543669 = 31543832
- 379 + 31543453 = 31543832
- 601 + 31543231 = 31543832
- 613 + 31543219 = 31543832
- 823 + 31543009 = 31543832
- 883 + 31542949 = 31543832
Showing the first eight; more decompositions exist.
