Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723694, here are decompositions:

17 + 8723677 = 8723694
41 + 8723653 = 8723694
101 + 8723593 = 8723694
163 + 8723531 = 8723694
173 + 8723521 = 8723694
197 + 8723497 = 8723694
211 + 8723483 = 8723694
257 + 8723437 = 8723694

Showing the first eight; more decompositions exist.
