Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606990, here are decompositions:

17 + 33606973 = 33606990
23 + 33606967 = 33606990
31 + 33606959 = 33606990
71 + 33606919 = 33606990
73 + 33606917 = 33606990
83 + 33606907 = 33606990
89 + 33606901 = 33606990
97 + 33606893 = 33606990

Showing the first eight; more decompositions exist.
