Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513972, here are decompositions:

13 + 33513959 = 33513972
29 + 33513943 = 33513972
59 + 33513913 = 33513972
61 + 33513911 = 33513972
71 + 33513901 = 33513972
83 + 33513889 = 33513972
109 + 33513863 = 33513972
113 + 33513859 = 33513972

Showing the first eight; more decompositions exist.
