Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618858, here are decompositions:

5 + 33618853 = 33618858
19 + 33618839 = 33618858
41 + 33618817 = 33618858
79 + 33618779 = 33618858
89 + 33618769 = 33618858
101 + 33618757 = 33618858
107 + 33618751 = 33618858
109 + 33618749 = 33618858

Showing the first eight; more decompositions exist.
