Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579780, here are decompositions:

11 + 33579769 = 33579780
43 + 33579737 = 33579780
67 + 33579713 = 33579780
109 + 33579671 = 33579780
131 + 33579649 = 33579780
137 + 33579643 = 33579780
151 + 33579629 = 33579780
163 + 33579617 = 33579780

Showing the first eight; more decompositions exist.
