Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723126, here are decompositions:

3 + 8723123 = 8723126
19 + 8723107 = 8723126
37 + 8723089 = 8723126
73 + 8723053 = 8723126
79 + 8723047 = 8723126
109 + 8723017 = 8723126
127 + 8722999 = 8723126
157 + 8722969 = 8723126

Showing the first eight; more decompositions exist.
