Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723122, here are decompositions:

41 + 8723081 = 8723122
59 + 8723063 = 8723122
131 + 8722991 = 8723122
173 + 8722949 = 8723122
263 + 8722859 = 8723122
281 + 8722841 = 8723122
293 + 8722829 = 8723122
383 + 8722739 = 8723122

Showing the first eight; more decompositions exist.
