Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513978, here are decompositions:

19 + 33513959 = 33513978
67 + 33513911 = 33513978
89 + 33513889 = 33513978
97 + 33513881 = 33513978
101 + 33513877 = 33513978
137 + 33513841 = 33513978
139 + 33513839 = 33513978
167 + 33513811 = 33513978

Showing the first eight; more decompositions exist.
