Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618386, here are decompositions:

7 + 33618379 = 33618386
73 + 33618313 = 33618386
79 + 33618307 = 33618386
97 + 33618289 = 33618386
283 + 33618103 = 33618386
349 + 33618037 = 33618386
379 + 33618007 = 33618386
523 + 33617863 = 33618386

Showing the first eight; more decompositions exist.
