Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047826, here are decompositions:

5 + 1047821 = 1047826
47 + 1047779 = 1047826
53 + 1047773 = 1047826
89 + 1047737 = 1047826
113 + 1047713 = 1047826
137 + 1047689 = 1047826
173 + 1047653 = 1047826
179 + 1047647 = 1047826

Showing the first eight; more decompositions exist.
