Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723206, here are decompositions:

3 + 8723203 = 8723206
83 + 8723123 = 8723206
257 + 8722949 = 8723206
293 + 8722913 = 8723206
347 + 8722859 = 8723206
449 + 8722757 = 8723206
467 + 8722739 = 8723206
563 + 8722643 = 8723206

Showing the first eight; more decompositions exist.
