Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650018, here are decompositions:

89 + 8649929 = 8650018
107 + 8649911 = 8650018
131 + 8649887 = 8650018
137 + 8649881 = 8650018
149 + 8649869 = 8650018
227 + 8649791 = 8650018
257 + 8649761 = 8650018
347 + 8649671 = 8650018

Showing the first eight; more decompositions exist.
