Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595548, here are decompositions:

269 + 31595279 = 31595548
311 + 31595237 = 31595548
359 + 31595189 = 31595548
557 + 31594991 = 31595548
587 + 31594961 = 31595548
617 + 31594931 = 31595548
641 + 31594907 = 31595548
821 + 31594727 = 31595548

Showing the first eight; more decompositions exist.
