Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600498, here are decompositions:

5 + 31600493 = 31600498
47 + 31600451 = 31600498
89 + 31600409 = 31600498
179 + 31600319 = 31600498
191 + 31600307 = 31600498
197 + 31600301 = 31600498
239 + 31600259 = 31600498
521 + 31599977 = 31600498

Showing the first eight; more decompositions exist.
