Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598856, here are decompositions:

17 + 31598839 = 31598856
67 + 31598789 = 31598856
73 + 31598783 = 31598856
103 + 31598753 = 31598856
139 + 31598717 = 31598856
173 + 31598683 = 31598856
313 + 31598543 = 31598856
337 + 31598519 = 31598856

Showing the first eight; more decompositions exist.
