Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516980, here are decompositions:

19 + 33516961 = 33516980
31 + 33516949 = 33516980
37 + 33516943 = 33516980
61 + 33516919 = 33516980
73 + 33516907 = 33516980
97 + 33516883 = 33516980
127 + 33516853 = 33516980
139 + 33516841 = 33516980

Showing the first eight; more decompositions exist.
