Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581820, here are decompositions:

7 + 33581813 = 33581820
29 + 33581791 = 33581820
53 + 33581767 = 33581820
59 + 33581761 = 33581820
79 + 33581741 = 33581820
113 + 33581707 = 33581820
127 + 33581693 = 33581820
149 + 33581671 = 33581820

Showing the first eight; more decompositions exist.
