Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502164, here are decompositions:

3 + 31502161 = 31502164
17 + 31502147 = 31502164
227 + 31501937 = 31502164
251 + 31501913 = 31502164
257 + 31501907 = 31502164
383 + 31501781 = 31502164
443 + 31501721 = 31502164
503 + 31501661 = 31502164

Showing the first eight; more decompositions exist.
