Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593608, here are decompositions:

19 + 31593589 = 31593608
37 + 31593571 = 31593608
97 + 31593511 = 31593608
499 + 31593109 = 31593608
577 + 31593031 = 31593608
661 + 31592947 = 31593608
811 + 31592797 = 31593608
829 + 31592779 = 31593608

Showing the first eight; more decompositions exist.
