Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616664, here are decompositions:

3 + 8616661 = 8616664
11 + 8616653 = 8616664
101 + 8616563 = 8616664
131 + 8616533 = 8616664
137 + 8616527 = 8616664
233 + 8616431 = 8616664
257 + 8616407 = 8616664
293 + 8616371 = 8616664

Showing the first eight; more decompositions exist.
