Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516978, here are decompositions:

17 + 33516961 = 33516978
29 + 33516949 = 33516978
31 + 33516947 = 33516978
59 + 33516919 = 33516978
71 + 33516907 = 33516978
109 + 33516869 = 33516978
127 + 33516851 = 33516978
137 + 33516841 = 33516978

Showing the first eight; more decompositions exist.
