Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599282, here are decompositions:

23 + 31599259 = 31599282
89 + 31599193 = 31599282
109 + 31599173 = 31599282
179 + 31599103 = 31599282
181 + 31599101 = 31599282
223 + 31599059 = 31599282
293 + 31598989 = 31599282
349 + 31598933 = 31599282

Showing the first eight; more decompositions exist.
