Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723224, here are decompositions:

11 + 8723213 = 8723224
101 + 8723123 = 8723224
233 + 8722991 = 8723224
311 + 8722913 = 8723224
347 + 8722877 = 8723224
383 + 8722841 = 8723224
467 + 8722757 = 8723224
563 + 8722661 = 8723224

Showing the first eight; more decompositions exist.
