Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593028, here are decompositions:

17 + 31593011 = 31593028
107 + 31592921 = 31593028
179 + 31592849 = 31593028
281 + 31592747 = 31593028
461 + 31592567 = 31593028
617 + 31592411 = 31593028
659 + 31592369 = 31593028
809 + 31592219 = 31593028

Showing the first eight; more decompositions exist.
