Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723164, here are decompositions:

41 + 8723123 = 8723164
83 + 8723081 = 8723164
101 + 8723063 = 8723164
173 + 8722991 = 8723164
251 + 8722913 = 8723164
491 + 8722673 = 8723164
503 + 8722661 = 8723164
521 + 8722643 = 8723164

Showing the first eight; more decompositions exist.
