Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723202, here are decompositions:

11 + 8723191 = 8723202
53 + 8723149 = 8723202
79 + 8723123 = 8723202
113 + 8723089 = 8723202
139 + 8723063 = 8723202
149 + 8723053 = 8723202
211 + 8722991 = 8723202
233 + 8722969 = 8723202

Showing the first eight; more decompositions exist.
