Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723656, here are decompositions:

3 + 8723653 = 8723656
17 + 8723639 = 8723656
47 + 8723609 = 8723656
173 + 8723483 = 8723656
197 + 8723459 = 8723656
233 + 8723423 = 8723656
257 + 8723399 = 8723656
269 + 8723387 = 8723656

Showing the first eight; more decompositions exist.
