Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047988, here are decompositions:

17 + 1047971 = 1047988
47 + 1047941 = 1047988
59 + 1047929 = 1047988
101 + 1047887 = 1047988
107 + 1047881 = 1047988
167 + 1047821 = 1047988
251 + 1047737 = 1047988
317 + 1047671 = 1047988

Showing the first eight; more decompositions exist.
