Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538990, here are decompositions:

3 + 33538987 = 33538990
11 + 33538979 = 33538990
41 + 33538949 = 33538990
53 + 33538937 = 33538990
71 + 33538919 = 33538990
83 + 33538907 = 33538990
131 + 33538859 = 33538990
167 + 33538823 = 33538990

Showing the first eight; more decompositions exist.
