Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020856, here are decompositions:

3 + 1020853 = 1020856
17 + 1020839 = 1020856
29 + 1020827 = 1020856
59 + 1020797 = 1020856
113 + 1020743 = 1020856
149 + 1020707 = 1020856
167 + 1020689 = 1020856
173 + 1020683 = 1020856

Showing the first eight; more decompositions exist.
