Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596874, here are decompositions:

17 + 31596857 = 31596874
53 + 31596821 = 31596874
131 + 31596743 = 31596874
167 + 31596707 = 31596874
263 + 31596611 = 31596874
401 + 31596473 = 31596874
461 + 31596413 = 31596874
557 + 31596317 = 31596874

Showing the first eight; more decompositions exist.
