Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581778, here are decompositions:

11 + 33581767 = 33581778
17 + 33581761 = 33581778
37 + 33581741 = 33581778
71 + 33581707 = 33581778
101 + 33581677 = 33581778
107 + 33581671 = 33581778
157 + 33581621 = 33581778
179 + 33581599 = 33581778

Showing the first eight; more decompositions exist.
