Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723416, here are decompositions:

17 + 8723399 = 8723416
29 + 8723387 = 8723416
113 + 8723303 = 8723416
173 + 8723243 = 8723416
293 + 8723123 = 8723416
353 + 8723063 = 8723416
467 + 8722949 = 8723416
503 + 8722913 = 8723416

Showing the first eight; more decompositions exist.
