Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489042, here are decompositions:

29 + 33489013 = 33489042
89 + 33488953 = 33489042
109 + 33488933 = 33489042
151 + 33488891 = 33489042
173 + 33488869 = 33489042
263 + 33488779 = 33489042
271 + 33488771 = 33489042
313 + 33488729 = 33489042

Showing the first eight; more decompositions exist.
