Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597116, here are decompositions:

17 + 31597099 = 31597116
73 + 31597043 = 31597116
113 + 31597003 = 31597116
139 + 31596977 = 31597116
167 + 31596949 = 31597116
193 + 31596923 = 31597116
227 + 31596889 = 31597116
233 + 31596883 = 31597116

Showing the first eight; more decompositions exist.
