Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161126, here are decompositions:

3 + 161123 = 161126
67 + 161059 = 161126
73 + 161053 = 161126
79 + 161047 = 161126
109 + 161017 = 161126
157 + 160969 = 161126
193 + 160933 = 161126
223 + 160903 = 161126

Showing the first eight; more decompositions exist.
