Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018228, here are decompositions:

5 + 1018223 = 1018228
11 + 1018217 = 1018228
131 + 1018097 = 1018228
137 + 1018091 = 1018228
269 + 1017959 = 1018228
347 + 1017881 = 1018228
401 + 1017827 = 1018228
479 + 1017749 = 1018228

Showing the first eight; more decompositions exist.
