Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156228, here are decompositions:

11 + 156217 = 156228
71 + 156157 = 156228
89 + 156139 = 156228
97 + 156131 = 156228
101 + 156127 = 156228
109 + 156119 = 156228
139 + 156089 = 156228
157 + 156071 = 156228

Showing the first eight; more decompositions exist.
