Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599354, here are decompositions:

5 + 31599349 = 31599354
13 + 31599341 = 31599354
41 + 31599313 = 31599354
47 + 31599307 = 31599354
107 + 31599247 = 31599354
181 + 31599173 = 31599354
197 + 31599157 = 31599354
251 + 31599103 = 31599354

Showing the first eight; more decompositions exist.
