Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615072, here are decompositions:

11 + 33615061 = 33615072
53 + 33615019 = 33615072
103 + 33614969 = 33615072
109 + 33614963 = 33615072
131 + 33614941 = 33615072
149 + 33614923 = 33615072
163 + 33614909 = 33615072
263 + 33614809 = 33615072

Showing the first eight; more decompositions exist.
