Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723556, here are decompositions:

5 + 8723551 = 8723556
59 + 8723497 = 8723556
73 + 8723483 = 8723556
97 + 8723459 = 8723556
137 + 8723419 = 8723556
157 + 8723399 = 8723556
197 + 8723359 = 8723556
239 + 8723317 = 8723556

Showing the first eight; more decompositions exist.
