Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616372, here are decompositions:

19 + 8616353 = 8616372
53 + 8616319 = 8616372
73 + 8616299 = 8616372
101 + 8616271 = 8616372
131 + 8616241 = 8616372
151 + 8616221 = 8616372
173 + 8616199 = 8616372
199 + 8616173 = 8616372

Showing the first eight; more decompositions exist.
