Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599372, here are decompositions:

19 + 31599353 = 31599372
23 + 31599349 = 31599372
31 + 31599341 = 31599372
59 + 31599313 = 31599372
113 + 31599259 = 31599372
179 + 31599193 = 31599372
199 + 31599173 = 31599372
269 + 31599103 = 31599372

Showing the first eight; more decompositions exist.
