Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597144, here are decompositions:

17 + 31597127 = 31597144
23 + 31597121 = 31597144
101 + 31597043 = 31597144
113 + 31597031 = 31597144
167 + 31596977 = 31597144
263 + 31596881 = 31597144
347 + 31596797 = 31597144
401 + 31596743 = 31597144

Showing the first eight; more decompositions exist.
