Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493386, here are decompositions:

13 + 33493373 = 33493386
23 + 33493363 = 33493386
79 + 33493307 = 33493386
103 + 33493283 = 33493386
107 + 33493279 = 33493386
163 + 33493223 = 33493386
229 + 33493157 = 33493386
233 + 33493153 = 33493386

Showing the first eight; more decompositions exist.
