Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 936138, here are decompositions:

11 + 936127 = 936138
19 + 936119 = 936138
41 + 936097 = 936138
109 + 936029 = 936138
131 + 936007 = 936138
139 + 935999 = 936138
167 + 935971 = 936138
239 + 935899 = 936138

Showing the first eight; more decompositions exist.
