Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564142, here are decompositions:

11 + 33564131 = 33564142
71 + 33564071 = 33564142
83 + 33564059 = 33564142
251 + 33563891 = 33564142
263 + 33563879 = 33564142
401 + 33563741 = 33564142
641 + 33563501 = 33564142
683 + 33563459 = 33564142

Showing the first eight; more decompositions exist.
