Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493390, here are decompositions:

3 + 33493387 = 33493390
17 + 33493373 = 33493390
83 + 33493307 = 33493390
107 + 33493283 = 33493390
137 + 33493253 = 33493390
149 + 33493241 = 33493390
167 + 33493223 = 33493390
173 + 33493217 = 33493390

Showing the first eight; more decompositions exist.
