Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706690, here are decompositions:

19 + 8706671 = 8706690
23 + 8706667 = 8706690
43 + 8706647 = 8706690
79 + 8706611 = 8706690
103 + 8706587 = 8706690
137 + 8706553 = 8706690
163 + 8706527 = 8706690
193 + 8706497 = 8706690

Showing the first eight; more decompositions exist.
