Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618818, here are decompositions:

61 + 33618757 = 33618818
67 + 33618751 = 33618818
241 + 33618577 = 33618818
367 + 33618451 = 33618818
379 + 33618439 = 33618818
397 + 33618421 = 33618818
439 + 33618379 = 33618818
487 + 33618331 = 33618818

Showing the first eight; more decompositions exist.
