Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597106, here are decompositions:

7 + 31597099 = 31597106
103 + 31597003 = 31597106
109 + 31596997 = 31597106
157 + 31596949 = 31597106
193 + 31596913 = 31597106
199 + 31596907 = 31597106
223 + 31596883 = 31597106
313 + 31596793 = 31597106

Showing the first eight; more decompositions exist.
