Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600252, here are decompositions:

59 + 31600193 = 31600252
149 + 31600103 = 31600252
191 + 31600061 = 31600252
251 + 31600001 = 31600252
293 + 31599959 = 31600252
311 + 31599941 = 31600252
443 + 31599809 = 31600252
479 + 31599773 = 31600252

Showing the first eight; more decompositions exist.
