Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723250, here are decompositions:

7 + 8723243 = 8723250
37 + 8723213 = 8723250
47 + 8723203 = 8723250
59 + 8723191 = 8723250
101 + 8723149 = 8723250
113 + 8723137 = 8723250
127 + 8723123 = 8723250
197 + 8723053 = 8723250

Showing the first eight; more decompositions exist.
