Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739216, here are decompositions:

7 + 8739209 = 8739216
19 + 8739197 = 8739216
23 + 8739193 = 8739216
29 + 8739187 = 8739216
47 + 8739169 = 8739216
53 + 8739163 = 8739216
89 + 8739127 = 8739216
97 + 8739119 = 8739216

Showing the first eight; more decompositions exist.
