Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620008, here are decompositions:

11 + 8619997 = 8620008
71 + 8619937 = 8620008
139 + 8619869 = 8620008
149 + 8619859 = 8620008
151 + 8619857 = 8620008
191 + 8619817 = 8620008
197 + 8619811 = 8620008
211 + 8619797 = 8620008

Showing the first eight; more decompositions exist.
