Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618420, here are decompositions:

7 + 33618413 = 33618420
41 + 33618379 = 33618420
61 + 33618359 = 33618420
89 + 33618331 = 33618420
97 + 33618323 = 33618420
103 + 33618317 = 33618420
107 + 33618313 = 33618420
113 + 33618307 = 33618420

Showing the first eight; more decompositions exist.
