Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515920, here are decompositions:

3 + 33515917 = 33515920
17 + 33515903 = 33515920
59 + 33515861 = 33515920
71 + 33515849 = 33515920
83 + 33515837 = 33515920
89 + 33515831 = 33515920
107 + 33515813 = 33515920
149 + 33515771 = 33515920

Showing the first eight; more decompositions exist.
