Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616628, here are decompositions:

29 + 8616599 = 8616628
101 + 8616527 = 8616628
197 + 8616431 = 8616628
257 + 8616371 = 8616628
347 + 8616281 = 8616628
431 + 8616197 = 8616628
479 + 8616149 = 8616628
557 + 8616071 = 8616628

Showing the first eight; more decompositions exist.
