Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485228, here are decompositions:

61 + 33485167 = 33485228
79 + 33485149 = 33485228
97 + 33485131 = 33485228
109 + 33485119 = 33485228
157 + 33485071 = 33485228
181 + 33485047 = 33485228
229 + 33484999 = 33485228
457 + 33484771 = 33485228

Showing the first eight; more decompositions exist.
