Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600456, here are decompositions:

3 + 31600453 = 31600456
5 + 31600451 = 31600456
47 + 31600409 = 31600456
137 + 31600319 = 31600456
149 + 31600307 = 31600456
179 + 31600277 = 31600456
197 + 31600259 = 31600456
263 + 31600193 = 31600456

Showing the first eight; more decompositions exist.
