Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048138, here are decompositions:

11 + 1048127 = 1048138
89 + 1048049 = 1048138
131 + 1048007 = 1048138
149 + 1047989 = 1048138
167 + 1047971 = 1048138
197 + 1047941 = 1048138
251 + 1047887 = 1048138
257 + 1047881 = 1048138

Showing the first eight; more decompositions exist.
