Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502010, here are decompositions:

31 + 31501979 = 31502010
53 + 31501957 = 31502010
73 + 31501937 = 31502010
97 + 31501913 = 31502010
103 + 31501907 = 31502010
131 + 31501879 = 31502010
149 + 31501861 = 31502010
179 + 31501831 = 31502010

Showing the first eight; more decompositions exist.
