Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047838, here are decompositions:

5 + 1047833 = 1047838
17 + 1047821 = 1047838
59 + 1047779 = 1047838
101 + 1047737 = 1047838
137 + 1047701 = 1047838
149 + 1047689 = 1047838
167 + 1047671 = 1047838
191 + 1047647 = 1047838

Showing the first eight; more decompositions exist.
