Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40620, here are decompositions:

11 + 40609 = 40620
23 + 40597 = 40620
29 + 40591 = 40620
37 + 40583 = 40620
43 + 40577 = 40620
61 + 40559 = 40620
89 + 40531 = 40620
101 + 40519 = 40620

Showing the first eight; more decompositions exist.
