Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609778, here are decompositions:

17 + 33609761 = 33609778
29 + 33609749 = 33609778
107 + 33609671 = 33609778
197 + 33609581 = 33609778
239 + 33609539 = 33609778
401 + 33609377 = 33609778
467 + 33609311 = 33609778
491 + 33609287 = 33609778

Showing the first eight; more decompositions exist.
