Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40790, here are decompositions:

3 + 40787 = 40790
19 + 40771 = 40790
31 + 40759 = 40790
97 + 40693 = 40790
151 + 40639 = 40790
163 + 40627 = 40790
181 + 40609 = 40790
193 + 40597 = 40790

Showing the first eight; more decompositions exist.
