Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579640, here are decompositions:

11 + 33579629 = 33579640
23 + 33579617 = 33579640
41 + 33579599 = 33579640
53 + 33579587 = 33579640
89 + 33579551 = 33579640
131 + 33579509 = 33579640
197 + 33579443 = 33579640
233 + 33579407 = 33579640

Showing the first eight; more decompositions exist.
