Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047128, here are decompositions:

31 + 1047097 = 1047128
67 + 1047061 = 1047128
97 + 1047031 = 1047128
151 + 1046977 = 1047128
211 + 1046917 = 1047128
331 + 1046797 = 1047128
337 + 1046791 = 1047128
349 + 1046779 = 1047128

Showing the first eight; more decompositions exist.
