Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489090, here are decompositions:

17 + 33489073 = 33489090
43 + 33489047 = 33489090
113 + 33488977 = 33489090
137 + 33488953 = 33489090
157 + 33488933 = 33489090
199 + 33488891 = 33489090
223 + 33488867 = 33489090
311 + 33488779 = 33489090

Showing the first eight; more decompositions exist.
