Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618986, here are decompositions:

43 + 33618943 = 33618986
67 + 33618919 = 33618986
97 + 33618889 = 33618986
229 + 33618757 = 33618986
409 + 33618577 = 33618986
547 + 33618439 = 33618986
607 + 33618379 = 33618986
673 + 33618313 = 33618986

Showing the first eight; more decompositions exist.
