Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538980, here are decompositions:

29 + 33538951 = 33538980
31 + 33538949 = 33538980
43 + 33538937 = 33538980
61 + 33538919 = 33538980
67 + 33538913 = 33538980
73 + 33538907 = 33538980
89 + 33538891 = 33538980
107 + 33538873 = 33538980

Showing the first eight; more decompositions exist.
