Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599552, here are decompositions:

53 + 31599499 = 31599552
113 + 31599439 = 31599552
163 + 31599389 = 31599552
199 + 31599353 = 31599552
211 + 31599341 = 31599552
239 + 31599313 = 31599552
293 + 31599259 = 31599552
359 + 31599193 = 31599552

Showing the first eight; more decompositions exist.
