Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493518, here are decompositions:

5 + 33493513 = 33493518
127 + 33493391 = 33493518
131 + 33493387 = 33493518
197 + 33493321 = 33493518
211 + 33493307 = 33493518
239 + 33493279 = 33493518
277 + 33493241 = 33493518
307 + 33493211 = 33493518

Showing the first eight; more decompositions exist.
