Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702928, here are decompositions:

89 + 8702839 = 8702928
107 + 8702821 = 8702928
109 + 8702819 = 8702928
151 + 8702777 = 8702928
181 + 8702747 = 8702928
197 + 8702731 = 8702928
229 + 8702699 = 8702928
239 + 8702689 = 8702928

Showing the first eight; more decompositions exist.
