Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985278, here are decompositions:

59 + 985219 = 985278
97 + 985181 = 985278
101 + 985177 = 985278
127 + 985151 = 985278
149 + 985129 = 985278
157 + 985121 = 985278
181 + 985097 = 985278
199 + 985079 = 985278

Showing the first eight; more decompositions exist.
