Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599300, here are decompositions:

41 + 31599259 = 31599300
53 + 31599247 = 31599300
107 + 31599193 = 31599300
127 + 31599173 = 31599300
197 + 31599103 = 31599300
199 + 31599101 = 31599300
241 + 31599059 = 31599300
311 + 31598989 = 31599300

Showing the first eight; more decompositions exist.
