Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33498990, here are decompositions:

11 + 33498979 = 33498990
59 + 33498931 = 33498990
79 + 33498911 = 33498990
89 + 33498901 = 33498990
97 + 33498893 = 33498990
103 + 33498887 = 33498990
113 + 33498877 = 33498990
127 + 33498863 = 33498990

Showing the first eight; more decompositions exist.
