Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502036, here are decompositions:

79 + 31501957 = 31502036
157 + 31501879 = 31502036
229 + 31501807 = 31502036
277 + 31501759 = 31502036
337 + 31501699 = 31502036
367 + 31501669 = 31502036
499 + 31501537 = 31502036
733 + 31501303 = 31502036

Showing the first eight; more decompositions exist.
