Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502952, here are decompositions:

11 + 31502941 = 31502952
29 + 31502923 = 31502952
71 + 31502881 = 31502952
191 + 31502761 = 31502952
251 + 31502701 = 31502952
263 + 31502689 = 31502952
293 + 31502659 = 31502952
389 + 31502563 = 31502952

Showing the first eight; more decompositions exist.
