Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600450, here are decompositions:

3 + 31600447 = 31600450
29 + 31600421 = 31600450
41 + 31600409 = 31600450
131 + 31600319 = 31600450
149 + 31600301 = 31600450
173 + 31600277 = 31600450
191 + 31600259 = 31600450
257 + 31600193 = 31600450

Showing the first eight; more decompositions exist.
