Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048128, here are decompositions:

5 + 1048123 = 1048128
79 + 1048049 = 1048128
101 + 1048027 = 1048128
131 + 1047997 = 1048128
139 + 1047989 = 1048128
149 + 1047979 = 1048128
157 + 1047971 = 1048128
167 + 1047961 = 1048128

Showing the first eight; more decompositions exist.
