Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502118, here are decompositions:

5 + 31502113 = 31502118
19 + 31502099 = 31502118
139 + 31501979 = 31502118
181 + 31501937 = 31502118
211 + 31501907 = 31502118
239 + 31501879 = 31502118
257 + 31501861 = 31502118
269 + 31501849 = 31502118

Showing the first eight; more decompositions exist.
