Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102284, here are decompositions:

31 + 102253 = 102284
43 + 102241 = 102284
67 + 102217 = 102284
103 + 102181 = 102284
163 + 102121 = 102284
181 + 102103 = 102284
223 + 102061 = 102284
241 + 102043 = 102284

Showing the first eight; more decompositions exist.
