Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502052, here are decompositions:

73 + 31501979 = 31502052
139 + 31501913 = 31502052
173 + 31501879 = 31502052
191 + 31501861 = 31502052
229 + 31501823 = 31502052
233 + 31501819 = 31502052
271 + 31501781 = 31502052
293 + 31501759 = 31502052

Showing the first eight; more decompositions exist.
