Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506138, here are decompositions:

7 + 33506131 = 33506138
157 + 33505981 = 33506138
199 + 33505939 = 33506138
271 + 33505867 = 33506138
349 + 33505789 = 33506138
571 + 33505567 = 33506138
619 + 33505519 = 33506138
691 + 33505447 = 33506138

Showing the first eight; more decompositions exist.
