Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538974, here are decompositions:

23 + 33538951 = 33538974
37 + 33538937 = 33538974
61 + 33538913 = 33538974
67 + 33538907 = 33538974
83 + 33538891 = 33538974
101 + 33538873 = 33538974
107 + 33538867 = 33538974
151 + 33538823 = 33538974

Showing the first eight; more decompositions exist.
