Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599964, here are decompositions:

5 + 31599959 = 31599964
23 + 31599941 = 31599964
47 + 31599917 = 31599964
191 + 31599773 = 31599964
197 + 31599767 = 31599964
257 + 31599707 = 31599964
281 + 31599683 = 31599964
293 + 31599671 = 31599964

Showing the first eight; more decompositions exist.
