Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40782, here are decompositions:

11 + 40771 = 40782
19 + 40763 = 40782
23 + 40759 = 40782
31 + 40751 = 40782
43 + 40739 = 40782
73 + 40709 = 40782
83 + 40699 = 40782
89 + 40693 = 40782

Showing the first eight; more decompositions exist.
