Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11028, here are decompositions:

41 + 10987 = 11028
71 + 10957 = 11028
79 + 10949 = 11028
89 + 10939 = 11028
137 + 10891 = 11028
139 + 10889 = 11028
167 + 10861 = 11028
181 + 10847 = 11028

Showing the first eight; more decompositions exist.
