Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031148, here are decompositions:

7 + 1031141 = 1031148
11 + 1031137 = 1031148
29 + 1031119 = 1031148
31 + 1031117 = 1031148
67 + 1031081 = 1031148
101 + 1031047 = 1031148
191 + 1030957 = 1031148
197 + 1030951 = 1031148

Showing the first eight; more decompositions exist.
