Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618238, here are decompositions:

29 + 33618209 = 33618238
47 + 33618191 = 33618238
89 + 33618149 = 33618238
239 + 33617999 = 33618238
281 + 33617957 = 33618238
317 + 33617921 = 33618238
419 + 33617819 = 33618238
431 + 33617807 = 33618238

Showing the first eight; more decompositions exist.
