Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618878, here are decompositions:

61 + 33618817 = 33618878
109 + 33618769 = 33618878
127 + 33618751 = 33618878
439 + 33618439 = 33618878
457 + 33618421 = 33618878
499 + 33618379 = 33618878
547 + 33618331 = 33618878
571 + 33618307 = 33618878

Showing the first eight; more decompositions exist.
