Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618800, here are decompositions:

31 + 33618769 = 33618800
43 + 33618757 = 33618800
157 + 33618643 = 33618800
223 + 33618577 = 33618800
307 + 33618493 = 33618800
349 + 33618451 = 33618800
379 + 33618421 = 33618800
421 + 33618379 = 33618800

Showing the first eight; more decompositions exist.
