Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612990, here are decompositions:

11 + 33612979 = 33612990
13 + 33612977 = 33612990
17 + 33612973 = 33612990
43 + 33612947 = 33612990
79 + 33612911 = 33612990
113 + 33612877 = 33612990
137 + 33612853 = 33612990
167 + 33612823 = 33612990

Showing the first eight; more decompositions exist.
