Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606972, here are decompositions:

5 + 33606967 = 33606972
13 + 33606959 = 33606972
31 + 33606941 = 33606972
53 + 33606919 = 33606972
71 + 33606901 = 33606972
73 + 33606899 = 33606972
79 + 33606893 = 33606972
83 + 33606889 = 33606972

Showing the first eight; more decompositions exist.
