Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31306, here are decompositions:

29 + 31277 = 31306
47 + 31259 = 31306
53 + 31253 = 31306
59 + 31247 = 31306
83 + 31223 = 31306
113 + 31193 = 31306
167 + 31139 = 31306
227 + 31079 = 31306

Showing the first eight; more decompositions exist.
