Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670690, here are decompositions:

11 + 8670679 = 8670690
23 + 8670667 = 8670690
37 + 8670653 = 8670690
53 + 8670637 = 8670690
71 + 8670619 = 8670690
79 + 8670611 = 8670690
101 + 8670589 = 8670690
107 + 8670583 = 8670690

Showing the first eight; more decompositions exist.
