Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600666, here are decompositions:

3 + 31600663 = 31600666
47 + 31600619 = 31600666
137 + 31600529 = 31600666
173 + 31600493 = 31600666
257 + 31600409 = 31600666
347 + 31600319 = 31600666
359 + 31600307 = 31600666
389 + 31600277 = 31600666

Showing the first eight; more decompositions exist.
