Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599444, here are decompositions:

5 + 31599439 = 31599444
13 + 31599431 = 31599444
103 + 31599341 = 31599444
131 + 31599313 = 31599444
137 + 31599307 = 31599444
197 + 31599247 = 31599444
251 + 31599193 = 31599444
271 + 31599173 = 31599444

Showing the first eight; more decompositions exist.
