Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538720, here are decompositions:

11 + 33538709 = 33538720
41 + 33538679 = 33538720
71 + 33538649 = 33538720
101 + 33538619 = 33538720
197 + 33538523 = 33538720
239 + 33538481 = 33538720
251 + 33538469 = 33538720
263 + 33538457 = 33538720

Showing the first eight; more decompositions exist.
