Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047928, here are decompositions:

5 + 1047923 = 1047928
41 + 1047887 = 1047928
47 + 1047881 = 1047928
107 + 1047821 = 1047928
149 + 1047779 = 1047928
191 + 1047737 = 1047928
227 + 1047701 = 1047928
239 + 1047689 = 1047928

Showing the first eight; more decompositions exist.
