Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31006, here are decompositions:

23 + 30983 = 31006
29 + 30977 = 31006
113 + 30893 = 31006
137 + 30869 = 31006
167 + 30839 = 31006
197 + 30809 = 31006
233 + 30773 = 31006
293 + 30713 = 31006

Showing the first eight; more decompositions exist.
