Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563972, here are decompositions:

61 + 33563911 = 33563972
109 + 33563863 = 33563972
139 + 33563833 = 33563972
151 + 33563821 = 33563972
163 + 33563809 = 33563972
223 + 33563749 = 33563972
283 + 33563689 = 33563972
439 + 33563533 = 33563972

Showing the first eight; more decompositions exist.
