Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502832, here are decompositions:

71 + 31502761 = 31502832
89 + 31502743 = 31502832
131 + 31502701 = 31502832
173 + 31502659 = 31502832
269 + 31502563 = 31502832
271 + 31502561 = 31502832
293 + 31502539 = 31502832
349 + 31502483 = 31502832

Showing the first eight; more decompositions exist.
