Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511780, here are decompositions:

11 + 33511769 = 33511780
23 + 33511757 = 33511780
53 + 33511727 = 33511780
83 + 33511697 = 33511780
101 + 33511679 = 33511780
167 + 33511613 = 33511780
179 + 33511601 = 33511780
233 + 33511547 = 33511780

Showing the first eight; more decompositions exist.
