Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719584, here are decompositions:

7 + 8719577 = 8719584
11 + 8719573 = 8719584
17 + 8719567 = 8719584
43 + 8719541 = 8719584
101 + 8719483 = 8719584
163 + 8719421 = 8719584
193 + 8719391 = 8719584
257 + 8719327 = 8719584

Showing the first eight; more decompositions exist.
