Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045148, here are decompositions:

19 + 1045129 = 1045148
31 + 1045117 = 1045148
37 + 1045111 = 1045148
67 + 1045081 = 1045148
127 + 1045021 = 1045148
151 + 1044997 = 1045148
271 + 1044877 = 1045148
337 + 1044811 = 1045148

Showing the first eight; more decompositions exist.
