Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723292, here are decompositions:

79 + 8723213 = 8723292
89 + 8723203 = 8723292
101 + 8723191 = 8723292
211 + 8723081 = 8723292
229 + 8723063 = 8723292
239 + 8723053 = 8723292
251 + 8723041 = 8723292
293 + 8722999 = 8723292

Showing the first eight; more decompositions exist.
