Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723234, here are decompositions:

31 + 8723203 = 8723234
43 + 8723191 = 8723234
97 + 8723137 = 8723234
127 + 8723107 = 8723234
181 + 8723053 = 8723234
193 + 8723041 = 8723234
241 + 8722993 = 8723234
523 + 8722711 = 8723234

Showing the first eight; more decompositions exist.
