Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600300, here are decompositions:

23 + 31600277 = 31600300
41 + 31600259 = 31600300
107 + 31600193 = 31600300
167 + 31600133 = 31600300
197 + 31600103 = 31600300
239 + 31600061 = 31600300
257 + 31600043 = 31600300
359 + 31599941 = 31600300

Showing the first eight; more decompositions exist.
