Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597324, here are decompositions:

41 + 31597283 = 31597324
71 + 31597253 = 31597324
173 + 31597151 = 31597324
197 + 31597127 = 31597324
281 + 31597043 = 31597324
293 + 31597031 = 31597324
347 + 31596977 = 31597324
401 + 31596923 = 31597324

Showing the first eight; more decompositions exist.
