Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616742, here are decompositions:

23 + 8616719 = 8616742
53 + 8616689 = 8616742
89 + 8616653 = 8616742
179 + 8616563 = 8616742
311 + 8616431 = 8616742
389 + 8616353 = 8616742
419 + 8616323 = 8616742
443 + 8616299 = 8616742

Showing the first eight; more decompositions exist.
