Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600600, here are decompositions:

71 + 31600529 = 31600600
89 + 31600511 = 31600600
107 + 31600493 = 31600600
149 + 31600451 = 31600600
179 + 31600421 = 31600600
191 + 31600409 = 31600600
281 + 31600319 = 31600600
293 + 31600307 = 31600600

Showing the first eight; more decompositions exist.
