Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599146, here are decompositions:

43 + 31599103 = 31599146
157 + 31598989 = 31599146
193 + 31598953 = 31599146
199 + 31598947 = 31599146
223 + 31598923 = 31599146
283 + 31598863 = 31599146
307 + 31598839 = 31599146
367 + 31598779 = 31599146

Showing the first eight; more decompositions exist.
