Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497252, here are decompositions:

23 + 31497229 = 31497252
29 + 31497223 = 31497252
113 + 31497139 = 31497252
181 + 31497071 = 31497252
251 + 31497001 = 31497252
263 + 31496989 = 31497252
331 + 31496921 = 31497252
379 + 31496873 = 31497252

Showing the first eight; more decompositions exist.
