Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513688, here are decompositions:

29 + 33513659 = 33513688
59 + 33513629 = 33513688
107 + 33513581 = 33513688
137 + 33513551 = 33513688
149 + 33513539 = 33513688
179 + 33513509 = 33513688
281 + 33513407 = 33513688
431 + 33513257 = 33513688

Showing the first eight; more decompositions exist.
