Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502112, here are decompositions:

13 + 31502099 = 31502112
29 + 31502083 = 31502112
199 + 31501913 = 31502112
233 + 31501879 = 31502112
251 + 31501861 = 31502112
263 + 31501849 = 31502112
281 + 31501831 = 31502112
293 + 31501819 = 31502112

Showing the first eight; more decompositions exist.
