Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31316, here are decompositions:

67 + 31249 = 31316
79 + 31237 = 31316
97 + 31219 = 31316
127 + 31189 = 31316
139 + 31177 = 31316
157 + 31159 = 31316
163 + 31153 = 31316
193 + 31123 = 31316

Showing the first eight; more decompositions exist.
