Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40650, here are decompositions:
- 11 + 40639 = 40650
- 13 + 40637 = 40650
- 23 + 40627 = 40650
- 41 + 40609 = 40650
- 53 + 40597 = 40650
- 59 + 40591 = 40650
- 67 + 40583 = 40650
- 73 + 40577 = 40650
Showing the first eight; more decompositions exist.
