Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502076, here are decompositions:

97 + 31501979 = 31502076
139 + 31501937 = 31502076
163 + 31501913 = 31502076
197 + 31501879 = 31502076
227 + 31501849 = 31502076
257 + 31501819 = 31502076
269 + 31501807 = 31502076
317 + 31501759 = 31502076

Showing the first eight; more decompositions exist.
