Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493980, here are decompositions:

7 + 33493973 = 33493980
11 + 33493969 = 33493980
17 + 33493963 = 33493980
59 + 33493921 = 33493980
67 + 33493913 = 33493980
73 + 33493907 = 33493980
89 + 33493891 = 33493980
103 + 33493877 = 33493980

Showing the first eight; more decompositions exist.
