Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618440, here are decompositions:

19 + 33618421 = 33618440
61 + 33618379 = 33618440
109 + 33618331 = 33618440
127 + 33618313 = 33618440
151 + 33618289 = 33618440
241 + 33618199 = 33618440
337 + 33618103 = 33618440
409 + 33618031 = 33618440

Showing the first eight; more decompositions exist.
