Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617872, here are decompositions:

53 + 33617819 = 33617872
251 + 33617621 = 33617872
269 + 33617603 = 33617872
311 + 33617561 = 33617872
383 + 33617489 = 33617872
461 + 33617411 = 33617872
479 + 33617393 = 33617872
809 + 33617063 = 33617872

Showing the first eight; more decompositions exist.
