Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618970, here are decompositions:

11 + 8618959 = 8618970
37 + 8618933 = 8618970
47 + 8618923 = 8618970
53 + 8618917 = 8618970
103 + 8618867 = 8618970
109 + 8618861 = 8618970
137 + 8618833 = 8618970
181 + 8618789 = 8618970

Showing the first eight; more decompositions exist.
