Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599396, here are decompositions:

7 + 31599389 = 31599396
43 + 31599353 = 31599396
47 + 31599349 = 31599396
83 + 31599313 = 31599396
89 + 31599307 = 31599396
137 + 31599259 = 31599396
149 + 31599247 = 31599396
223 + 31599173 = 31599396

Showing the first eight; more decompositions exist.
