Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136818, here are decompositions:

5 + 136813 = 136818
7 + 136811 = 136818
41 + 136777 = 136818
67 + 136751 = 136818
79 + 136739 = 136818
107 + 136711 = 136818
109 + 136709 = 136818
127 + 136691 = 136818

Showing the first eight; more decompositions exist.
