Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599500, here are decompositions:

13 + 31599487 = 31599500
61 + 31599439 = 31599500
151 + 31599349 = 31599500
193 + 31599307 = 31599500
241 + 31599259 = 31599500
307 + 31599193 = 31599500
397 + 31599103 = 31599500
547 + 31598953 = 31599500

Showing the first eight; more decompositions exist.
