Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502106, here are decompositions:

7 + 31502099 = 31502106
23 + 31502083 = 31502106
127 + 31501979 = 31502106
149 + 31501957 = 31502106
193 + 31501913 = 31502106
199 + 31501907 = 31502106
227 + 31501879 = 31502106
257 + 31501849 = 31502106

Showing the first eight; more decompositions exist.
