Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493290, here are decompositions:

7 + 33493283 = 33493290
11 + 33493279 = 33493290
37 + 33493253 = 33493290
67 + 33493223 = 33493290
73 + 33493217 = 33493290
79 + 33493211 = 33493290
107 + 33493183 = 33493290
137 + 33493153 = 33493290

Showing the first eight; more decompositions exist.
