Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597050, here are decompositions:

7 + 31597043 = 31597050
19 + 31597031 = 31597050
47 + 31597003 = 31597050
53 + 31596997 = 31597050
59 + 31596991 = 31597050
73 + 31596977 = 31597050
101 + 31596949 = 31597050
127 + 31596923 = 31597050

Showing the first eight; more decompositions exist.
