Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620490, here are decompositions:

11 + 33620479 = 33620490
17 + 33620473 = 33620490
19 + 33620471 = 33620490
23 + 33620467 = 33620490
31 + 33620459 = 33620490
41 + 33620449 = 33620490
53 + 33620437 = 33620490
61 + 33620429 = 33620490

Showing the first eight; more decompositions exist.
