Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489940, here are decompositions:

83 + 33489857 = 33489940
101 + 33489839 = 33489940
149 + 33489791 = 33489940
227 + 33489713 = 33489940
233 + 33489707 = 33489940
251 + 33489689 = 33489940
257 + 33489683 = 33489940
311 + 33489629 = 33489940

Showing the first eight; more decompositions exist.
