Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11228, here are decompositions:

31 + 11197 = 11228
67 + 11161 = 11228
79 + 11149 = 11228
97 + 11131 = 11228
109 + 11119 = 11228
157 + 11071 = 11228
181 + 11047 = 11228
241 + 10987 = 11228

Showing the first eight; more decompositions exist.
