Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597222, here are decompositions:

23 + 31597199 = 31597222
71 + 31597151 = 31597222
101 + 31597121 = 31597222
179 + 31597043 = 31597222
191 + 31597031 = 31597222
383 + 31596839 = 31597222
401 + 31596821 = 31597222
479 + 31596743 = 31597222

Showing the first eight; more decompositions exist.
