Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613128, here are decompositions:

47 + 33613081 = 33613128
79 + 33613049 = 33613128
89 + 33613039 = 33613128
97 + 33613031 = 33613128
137 + 33612991 = 33613128
149 + 33612979 = 33613128
151 + 33612977 = 33613128
181 + 33612947 = 33613128

Showing the first eight; more decompositions exist.
