Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593964, here are decompositions:

5 + 31593959 = 31593964
11 + 31593953 = 31593964
131 + 31593833 = 31593964
167 + 31593797 = 31593964
197 + 31593767 = 31593964
317 + 31593647 = 31593964
401 + 31593563 = 31593964
431 + 31593533 = 31593964

Showing the first eight; more decompositions exist.
