Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618866, here are decompositions:

13 + 33618853 = 33618866
97 + 33618769 = 33618866
109 + 33618757 = 33618866
223 + 33618643 = 33618866
373 + 33618493 = 33618866
487 + 33618379 = 33618866
577 + 33618289 = 33618866
727 + 33618139 = 33618866

Showing the first eight; more decompositions exist.
