Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613818, here are decompositions:

11 + 33613807 = 33613818
37 + 33613781 = 33613818
61 + 33613757 = 33613818
67 + 33613751 = 33613818
79 + 33613739 = 33613818
107 + 33613711 = 33613818
137 + 33613681 = 33613818
157 + 33613661 = 33613818

Showing the first eight; more decompositions exist.
