Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513990, here are decompositions:

11 + 33513979 = 33513990
31 + 33513959 = 33513990
47 + 33513943 = 33513990
79 + 33513911 = 33513990
89 + 33513901 = 33513990
101 + 33513889 = 33513990
109 + 33513881 = 33513990
113 + 33513877 = 33513990

Showing the first eight; more decompositions exist.
