Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538986, here are decompositions:

7 + 33538979 = 33538986
37 + 33538949 = 33538986
67 + 33538919 = 33538986
73 + 33538913 = 33538986
79 + 33538907 = 33538986
113 + 33538873 = 33538986
127 + 33538859 = 33538986
163 + 33538823 = 33538986

Showing the first eight; more decompositions exist.
