Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599264, here are decompositions:

5 + 31599259 = 31599264
17 + 31599247 = 31599264
71 + 31599193 = 31599264
107 + 31599157 = 31599264
163 + 31599101 = 31599264
311 + 31598953 = 31599264
317 + 31598947 = 31599264
331 + 31598933 = 31599264

Showing the first eight; more decompositions exist.
