Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723146, here are decompositions:

23 + 8723123 = 8723146
83 + 8723063 = 8723146
197 + 8722949 = 8723146
233 + 8722913 = 8723146
269 + 8722877 = 8723146
317 + 8722829 = 8723146
347 + 8722799 = 8723146
389 + 8722757 = 8723146

Showing the first eight; more decompositions exist.
