Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11282, here are decompositions:

3 + 11279 = 11282
31 + 11251 = 11282
43 + 11239 = 11282
109 + 11173 = 11282
151 + 11131 = 11282
163 + 11119 = 11282
199 + 11083 = 11282
211 + 11071 = 11282

Showing the first eight; more decompositions exist.
