Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616748, here are decompositions:

29 + 8616719 = 8616748
59 + 8616689 = 8616748
149 + 8616599 = 8616748
317 + 8616431 = 8616748
449 + 8616299 = 8616748
467 + 8616281 = 8616748
599 + 8616149 = 8616748
617 + 8616131 = 8616748

Showing the first eight; more decompositions exist.
