Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723258, here are decompositions:

67 + 8723191 = 8723258
109 + 8723149 = 8723258
151 + 8723107 = 8723258
211 + 8723047 = 8723258
241 + 8723017 = 8723258
277 + 8722981 = 8723258
367 + 8722891 = 8723258
547 + 8722711 = 8723258

Showing the first eight; more decompositions exist.
