Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502176, here are decompositions:

29 + 31502147 = 31502176
47 + 31502129 = 31502176
197 + 31501979 = 31502176
239 + 31501937 = 31502176
263 + 31501913 = 31502176
269 + 31501907 = 31502176
353 + 31501823 = 31502176
449 + 31501727 = 31502176

Showing the first eight; more decompositions exist.
