Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543634, here are decompositions:
- 103 + 31543531 = 31543634
- 181 + 31543453 = 31543634
- 643 + 31542991 = 31543634
- 691 + 31542943 = 31543634
- 757 + 31542877 = 31543634
- 823 + 31542811 = 31543634
- 907 + 31542727 = 31543634
- 937 + 31542697 = 31543634
Showing the first eight; more decompositions exist.
