Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723528, here are decompositions:

7 + 8723521 = 8723528
31 + 8723497 = 8723528
109 + 8723419 = 8723528
181 + 8723347 = 8723528
211 + 8723317 = 8723528
337 + 8723191 = 8723528
379 + 8723149 = 8723528
421 + 8723107 = 8723528

Showing the first eight; more decompositions exist.
