Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618780, here are decompositions:

7 + 33618773 = 33618780
11 + 33618769 = 33618780
23 + 33618757 = 33618780
29 + 33618751 = 33618780
31 + 33618749 = 33618780
43 + 33618737 = 33618780
61 + 33618719 = 33618780
109 + 33618671 = 33618780

Showing the first eight; more decompositions exist.
