Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639090, here are decompositions:

79 + 8639011 = 8639090
139 + 8638951 = 8639090
157 + 8638933 = 8639090
181 + 8638909 = 8639090
199 + 8638891 = 8639090
223 + 8638867 = 8639090
241 + 8638849 = 8639090
283 + 8638807 = 8639090

Showing the first eight; more decompositions exist.
