Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597070, here are decompositions:

19 + 31597051 = 31597070
67 + 31597003 = 31597070
73 + 31596997 = 31597070
79 + 31596991 = 31597070
157 + 31596913 = 31597070
163 + 31596907 = 31597070
181 + 31596889 = 31597070
223 + 31596847 = 31597070

Showing the first eight; more decompositions exist.
