Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715690, here are decompositions:

17 + 8715673 = 8715690
19 + 8715671 = 8715690
23 + 8715667 = 8715690
31 + 8715659 = 8715690
37 + 8715653 = 8715690
41 + 8715649 = 8715690
43 + 8715647 = 8715690
73 + 8715617 = 8715690

Showing the first eight; more decompositions exist.
