Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719230, here are decompositions:

7 + 8719223 = 8719230
11 + 8719219 = 8719230
17 + 8719213 = 8719230
19 + 8719211 = 8719230
31 + 8719199 = 8719230
43 + 8719187 = 8719230
53 + 8719177 = 8719230
67 + 8719163 = 8719230

Showing the first eight; more decompositions exist.
