Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618438, here are decompositions:

17 + 33618421 = 33618438
59 + 33618379 = 33618438
79 + 33618359 = 33618438
107 + 33618331 = 33618438
109 + 33618329 = 33618438
131 + 33618307 = 33618438
149 + 33618289 = 33618438
229 + 33618209 = 33618438

Showing the first eight; more decompositions exist.
