Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40730, here are decompositions:

31 + 40699 = 40730
37 + 40693 = 40730
103 + 40627 = 40730
139 + 40591 = 40730
199 + 40531 = 40730
211 + 40519 = 40730
223 + 40507 = 40730
271 + 40459 = 40730

Showing the first eight; more decompositions exist.
