Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723174, here are decompositions:

37 + 8723137 = 8723174
67 + 8723107 = 8723174
127 + 8723047 = 8723174
157 + 8723017 = 8723174
181 + 8722993 = 8723174
193 + 8722981 = 8723174
283 + 8722891 = 8723174
463 + 8722711 = 8723174

Showing the first eight; more decompositions exist.
