Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670756, here are decompositions:

5 + 8670751 = 8670756
13 + 8670743 = 8670756
43 + 8670713 = 8670756
47 + 8670709 = 8670756
53 + 8670703 = 8670756
89 + 8670667 = 8670756
103 + 8670653 = 8670756
137 + 8670619 = 8670756

Showing the first eight; more decompositions exist.
