Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517980, here are decompositions:

37 + 33517943 = 33517980
59 + 33517921 = 33517980
73 + 33517907 = 33517980
79 + 33517901 = 33517980
101 + 33517879 = 33517980
107 + 33517873 = 33517980
109 + 33517871 = 33517980
131 + 33517849 = 33517980

Showing the first eight; more decompositions exist.
