Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597174, here are decompositions:

23 + 31597151 = 31597174
47 + 31597127 = 31597174
53 + 31597121 = 31597174
131 + 31597043 = 31597174
197 + 31596977 = 31597174
251 + 31596923 = 31597174
293 + 31596881 = 31597174
317 + 31596857 = 31597174

Showing the first eight; more decompositions exist.
