Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618910, here are decompositions:

17 + 8618893 = 8618910
31 + 8618879 = 8618910
43 + 8618867 = 8618910
59 + 8618851 = 8618910
101 + 8618809 = 8618910
127 + 8618783 = 8618910
151 + 8618759 = 8618910
163 + 8618747 = 8618910

Showing the first eight; more decompositions exist.
