Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723230, here are decompositions:

17 + 8723213 = 8723230
107 + 8723123 = 8723230
149 + 8723081 = 8723230
167 + 8723063 = 8723230
239 + 8722991 = 8723230
281 + 8722949 = 8723230
317 + 8722913 = 8723230
353 + 8722877 = 8723230

Showing the first eight; more decompositions exist.
