Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33492990, here are decompositions:

19 + 33492971 = 33492990
67 + 33492923 = 33492990
73 + 33492917 = 33492990
101 + 33492889 = 33492990
103 + 33492887 = 33492990
127 + 33492863 = 33492990
197 + 33492793 = 33492990
199 + 33492791 = 33492990

Showing the first eight; more decompositions exist.
