Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502898, here are decompositions:

17 + 31502881 = 31502898
41 + 31502857 = 31502898
137 + 31502761 = 31502898
197 + 31502701 = 31502898
199 + 31502699 = 31502898
211 + 31502687 = 31502898
239 + 31502659 = 31502898
311 + 31502587 = 31502898

Showing the first eight; more decompositions exist.
