Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502588, here are decompositions:

31 + 31502557 = 31502588
157 + 31502431 = 31502588
277 + 31502311 = 31502588
457 + 31502131 = 31502588
631 + 31501957 = 31502588
709 + 31501879 = 31502588
727 + 31501861 = 31502588
739 + 31501849 = 31502588

Showing the first eight; more decompositions exist.
