Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612228, here are decompositions:

11 + 33612217 = 33612228
17 + 33612211 = 33612228
29 + 33612199 = 33612228
71 + 33612157 = 33612228
127 + 33612101 = 33612228
149 + 33612079 = 33612228
229 + 33611999 = 33612228
241 + 33611987 = 33612228

Showing the first eight; more decompositions exist.
