Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618918, here are decompositions:

29 + 33618889 = 33618918
31 + 33618887 = 33618918
61 + 33618857 = 33618918
79 + 33618839 = 33618918
101 + 33618817 = 33618918
139 + 33618779 = 33618918
149 + 33618769 = 33618918
167 + 33618751 = 33618918

Showing the first eight; more decompositions exist.
