Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719224, here are decompositions:

5 + 8719219 = 8719224
11 + 8719213 = 8719224
13 + 8719211 = 8719224
37 + 8719187 = 8719224
47 + 8719177 = 8719224
61 + 8719163 = 8719224
83 + 8719141 = 8719224
97 + 8719127 = 8719224

Showing the first eight; more decompositions exist.
