Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986228, here are decompositions:

31 + 986197 = 986228
37 + 986191 = 986228
79 + 986149 = 986228
97 + 986131 = 986228
127 + 986101 = 986228
157 + 986071 = 986228
181 + 986047 = 986228
277 + 985951 = 986228

Showing the first eight; more decompositions exist.
