Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931278, here are decompositions:

11 + 931267 = 931278
37 + 931241 = 931278
41 + 931237 = 931278
79 + 931199 = 931278
97 + 931181 = 931278
109 + 931169 = 931278
149 + 931129 = 931278
151 + 931127 = 931278

Showing the first eight; more decompositions exist.
