Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689944, here are decompositions:

101 + 8689843 = 8689944
103 + 8689841 = 8689944
127 + 8689817 = 8689944
167 + 8689777 = 8689944
191 + 8689753 = 8689944
233 + 8689711 = 8689944
257 + 8689687 = 8689944
271 + 8689673 = 8689944

Showing the first eight; more decompositions exist.
