Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513442, here are decompositions:

3 + 33513439 = 33513442
41 + 33513401 = 33513442
239 + 33513203 = 33513442
419 + 33513023 = 33513442
503 + 33512939 = 33513442
569 + 33512873 = 33513442
659 + 33512783 = 33513442
719 + 33512723 = 33513442

Showing the first eight; more decompositions exist.
