Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11018, here are decompositions:

31 + 10987 = 11018
61 + 10957 = 11018
79 + 10939 = 11018
109 + 10909 = 11018
127 + 10891 = 11018
151 + 10867 = 11018
157 + 10861 = 11018
181 + 10837 = 11018

Showing the first eight; more decompositions exist.
