Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126162, here are decompositions:

11 + 126151 = 126162
19 + 126143 = 126162
31 + 126131 = 126162
83 + 126079 = 126162
131 + 126031 = 126162
139 + 126023 = 126162
149 + 126013 = 126162
151 + 126011 = 126162

Showing the first eight; more decompositions exist.
