Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723106, here are decompositions:

17 + 8723089 = 8723106
43 + 8723063 = 8723106
53 + 8723053 = 8723106
59 + 8723047 = 8723106
89 + 8723017 = 8723106
107 + 8722999 = 8723106
113 + 8722993 = 8723106
137 + 8722969 = 8723106

Showing the first eight; more decompositions exist.
