Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616672, here are decompositions:

11 + 8616661 = 8616672
19 + 8616653 = 8616672
73 + 8616599 = 8616672
109 + 8616563 = 8616672
131 + 8616541 = 8616672
139 + 8616533 = 8616672
173 + 8616499 = 8616672
179 + 8616493 = 8616672

Showing the first eight; more decompositions exist.
