Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597080, here are decompositions:

29 + 31597051 = 31597080
37 + 31597043 = 31597080
83 + 31596997 = 31597080
89 + 31596991 = 31597080
103 + 31596977 = 31597080
131 + 31596949 = 31597080
157 + 31596923 = 31597080
167 + 31596913 = 31597080

Showing the first eight; more decompositions exist.
