Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726690, here are decompositions:

3 + 8726687 = 8726690
13 + 8726677 = 8726690
19 + 8726671 = 8726690
43 + 8726647 = 8726690
79 + 8726611 = 8726690
103 + 8726587 = 8726690
157 + 8726533 = 8726690
163 + 8726527 = 8726690

Showing the first eight; more decompositions exist.
