Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597046, here are decompositions:

3 + 31597043 = 31597046
43 + 31597003 = 31597046
97 + 31596949 = 31597046
139 + 31596907 = 31597046
157 + 31596889 = 31597046
163 + 31596883 = 31597046
199 + 31596847 = 31597046
277 + 31596769 = 31597046

Showing the first eight; more decompositions exist.
