Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597194, here are decompositions:

17 + 31597177 = 31597194
43 + 31597151 = 31597194
67 + 31597127 = 31597194
73 + 31597121 = 31597194
113 + 31597081 = 31597194
151 + 31597043 = 31597194
163 + 31597031 = 31597194
191 + 31597003 = 31597194

Showing the first eight; more decompositions exist.
