Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618788, here are decompositions:

19 + 33618769 = 33618788
31 + 33618757 = 33618788
37 + 33618751 = 33618788
211 + 33618577 = 33618788
337 + 33618451 = 33618788
349 + 33618439 = 33618788
367 + 33618421 = 33618788
409 + 33618379 = 33618788

Showing the first eight; more decompositions exist.
