Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596248, here are decompositions:

97 + 31596151 = 31596248
127 + 31596121 = 31596248
181 + 31596067 = 31596248
199 + 31596049 = 31596248
241 + 31596007 = 31596248
367 + 31595881 = 31596248
379 + 31595869 = 31596248
547 + 31595701 = 31596248

Showing the first eight; more decompositions exist.
