Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502486, here are decompositions:

3 + 31502483 = 31502486
157 + 31502329 = 31502486
199 + 31502287 = 31502486
373 + 31502113 = 31502486
607 + 31501879 = 31502486
727 + 31501759 = 31502486
787 + 31501699 = 31502486
853 + 31501633 = 31502486

Showing the first eight; more decompositions exist.
