Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40722, here are decompositions:
- 13 + 40709 = 40722
- 23 + 40699 = 40722
- 29 + 40693 = 40722
- 83 + 40639 = 40722
- 113 + 40609 = 40722
- 131 + 40591 = 40722
- 139 + 40583 = 40722
- 163 + 40559 = 40722
Showing the first eight; more decompositions exist.
