Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031228, here are decompositions:

67 + 1031161 = 1031228
109 + 1031119 = 1031228
181 + 1031047 = 1031228
241 + 1030987 = 1031228
271 + 1030957 = 1031228
277 + 1030951 = 1031228
397 + 1030831 = 1031228
487 + 1030741 = 1031228

Showing the first eight; more decompositions exist.
