Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40630, here are decompositions:
- 3 + 40627 = 40630
- 47 + 40583 = 40630
- 53 + 40577 = 40630
- 71 + 40559 = 40630
- 101 + 40529 = 40630
- 131 + 40499 = 40630
- 137 + 40493 = 40630
- 197 + 40433 = 40630
Showing the first eight; more decompositions exist.
