Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502252, here are decompositions:

139 + 31502113 = 31502252
373 + 31501879 = 31502252
421 + 31501831 = 31502252
433 + 31501819 = 31502252
619 + 31501633 = 31502252
631 + 31501621 = 31502252
853 + 31501399 = 31502252
919 + 31501333 = 31502252

Showing the first eight; more decompositions exist.
