Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31286, here are decompositions:

19 + 31267 = 31286
37 + 31249 = 31286
67 + 31219 = 31286
97 + 31189 = 31286
103 + 31183 = 31286
109 + 31177 = 31286
127 + 31159 = 31286
139 + 31147 = 31286

Showing the first eight; more decompositions exist.
