Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723274, here are decompositions:

31 + 8723243 = 8723274
61 + 8723213 = 8723274
71 + 8723203 = 8723274
83 + 8723191 = 8723274
137 + 8723137 = 8723274
151 + 8723123 = 8723274
167 + 8723107 = 8723274
193 + 8723081 = 8723274

Showing the first eight; more decompositions exist.
