Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617944, here are decompositions:

11 + 8617933 = 8617944
17 + 8617927 = 8617944
67 + 8617877 = 8617944
73 + 8617871 = 8617944
107 + 8617837 = 8617944
157 + 8617787 = 8617944
191 + 8617753 = 8617944
241 + 8617703 = 8617944

Showing the first eight; more decompositions exist.
