Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596080, here are decompositions:

13 + 31596067 = 31596080
31 + 31596049 = 31596080
73 + 31596007 = 31596080
97 + 31595983 = 31596080
151 + 31595929 = 31596080
199 + 31595881 = 31596080
211 + 31595869 = 31596080
349 + 31595731 = 31596080

Showing the first eight; more decompositions exist.
