Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723896, here are decompositions:

3 + 8723893 = 8723896
17 + 8723879 = 8723896
89 + 8723807 = 8723896
107 + 8723789 = 8723896
257 + 8723639 = 8723896
509 + 8723387 = 8723896
593 + 8723303 = 8723896
653 + 8723243 = 8723896

Showing the first eight; more decompositions exist.
