Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567396, here are decompositions:

83 + 31567313 = 31567396
239 + 31567157 = 31567396
347 + 31567049 = 31567396
353 + 31567043 = 31567396
557 + 31566839 = 31567396
569 + 31566827 = 31567396
593 + 31566803 = 31567396
599 + 31566797 = 31567396

Showing the first eight; more decompositions exist.
