Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547228, here are decompositions:

59 + 33547169 = 33547228
89 + 33547139 = 33547228
131 + 33547097 = 33547228
251 + 33546977 = 33547228
311 + 33546917 = 33547228
389 + 33546839 = 33547228
557 + 33546671 = 33547228
569 + 33546659 = 33547228

Showing the first eight; more decompositions exist.
