Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511828, here are decompositions:

59 + 33511769 = 33511828
71 + 33511757 = 33511828
101 + 33511727 = 33511828
131 + 33511697 = 33511828
149 + 33511679 = 33511828
167 + 33511661 = 33511828
227 + 33511601 = 33511828
257 + 33511571 = 33511828

Showing the first eight; more decompositions exist.
