Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723244, here are decompositions:

31 + 8723213 = 8723244
41 + 8723203 = 8723244
53 + 8723191 = 8723244
107 + 8723137 = 8723244
137 + 8723107 = 8723244
163 + 8723081 = 8723244
181 + 8723063 = 8723244
191 + 8723053 = 8723244

Showing the first eight; more decompositions exist.
