Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723212, here are decompositions:

89 + 8723123 = 8723212
131 + 8723081 = 8723212
149 + 8723063 = 8723212
263 + 8722949 = 8723212
353 + 8722859 = 8723212
383 + 8722829 = 8723212
569 + 8722643 = 8723212
599 + 8722613 = 8723212

Showing the first eight; more decompositions exist.
