Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670750, here are decompositions:

7 + 8670743 = 8670750
37 + 8670713 = 8670750
41 + 8670709 = 8670750
47 + 8670703 = 8670750
71 + 8670679 = 8670750
83 + 8670667 = 8670750
97 + 8670653 = 8670750
113 + 8670637 = 8670750

Showing the first eight; more decompositions exist.
