Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980228, here are decompositions:

31 + 980197 = 980228
79 + 980149 = 980228
97 + 980131 = 980228
157 + 980071 = 980228
181 + 980047 = 980228
241 + 979987 = 980228
307 + 979921 = 980228
397 + 979831 = 980228

Showing the first eight; more decompositions exist.
