Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597462, here are decompositions:

179 + 31597283 = 31597462
263 + 31597199 = 31597462
311 + 31597151 = 31597462
419 + 31597043 = 31597462
431 + 31597031 = 31597462
563 + 31596899 = 31597462
641 + 31596821 = 31597462
719 + 31596743 = 31597462

Showing the first eight; more decompositions exist.
