Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618450, here are decompositions:

7 + 33618443 = 33618450
11 + 33618439 = 33618450
29 + 33618421 = 33618450
37 + 33618413 = 33618450
71 + 33618379 = 33618450
127 + 33618323 = 33618450
137 + 33618313 = 33618450
199 + 33618251 = 33618450

Showing the first eight; more decompositions exist.
