Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047802, here are decompositions:

23 + 1047779 = 1047802
29 + 1047773 = 1047802
89 + 1047713 = 1047802
101 + 1047701 = 1047802
113 + 1047689 = 1047802
131 + 1047671 = 1047802
149 + 1047653 = 1047802
251 + 1047551 = 1047802

Showing the first eight; more decompositions exist.
