Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618390, here are decompositions:

11 + 33618379 = 33618390
31 + 33618359 = 33618390
59 + 33618331 = 33618390
61 + 33618329 = 33618390
67 + 33618323 = 33618390
73 + 33618317 = 33618390
83 + 33618307 = 33618390
101 + 33618289 = 33618390

Showing the first eight; more decompositions exist.
