Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599252, here are decompositions:

5 + 31599247 = 31599252
59 + 31599193 = 31599252
79 + 31599173 = 31599252
149 + 31599103 = 31599252
151 + 31599101 = 31599252
193 + 31599059 = 31599252
263 + 31598989 = 31599252
313 + 31598939 = 31599252

Showing the first eight; more decompositions exist.
