Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597062, here are decompositions:

11 + 31597051 = 31597062
19 + 31597043 = 31597062
31 + 31597031 = 31597062
59 + 31597003 = 31597062
71 + 31596991 = 31597062
113 + 31596949 = 31597062
139 + 31596923 = 31597062
149 + 31596913 = 31597062

Showing the first eight; more decompositions exist.
