Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616690, here are decompositions:

11 + 8616679 = 8616690
29 + 8616661 = 8616690
37 + 8616653 = 8616690
127 + 8616563 = 8616690
149 + 8616541 = 8616690
157 + 8616533 = 8616690
163 + 8616527 = 8616690
191 + 8616499 = 8616690

Showing the first eight; more decompositions exist.
