Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513188, here are decompositions:

61 + 33513127 = 33513188
211 + 33512977 = 33513188
229 + 33512959 = 33513188
307 + 33512881 = 33513188
349 + 33512839 = 33513188
409 + 33512779 = 33513188
547 + 33512641 = 33513188
571 + 33512617 = 33513188

Showing the first eight; more decompositions exist.
