Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027228, here are decompositions:

5 + 1027223 = 1027228
17 + 1027211 = 1027228
29 + 1027199 = 1027228
47 + 1027181 = 1027228
89 + 1027139 = 1027228
101 + 1027127 = 1027228
131 + 1027097 = 1027228
197 + 1027031 = 1027228

Showing the first eight; more decompositions exist.
