Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047888, here are decompositions:

5 + 1047883 = 1047888
7 + 1047881 = 1047888
29 + 1047859 = 1047888
47 + 1047841 = 1047888
67 + 1047821 = 1047888
109 + 1047779 = 1047888
137 + 1047751 = 1047888
151 + 1047737 = 1047888

Showing the first eight; more decompositions exist.
