Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723104, here are decompositions:

23 + 8723081 = 8723104
41 + 8723063 = 8723104
113 + 8722991 = 8723104
191 + 8722913 = 8723104
227 + 8722877 = 8723104
263 + 8722841 = 8723104
347 + 8722757 = 8723104
431 + 8722673 = 8723104

Showing the first eight; more decompositions exist.
