Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483250, here are decompositions:

13 + 31483237 = 31483250
37 + 31483213 = 31483250
157 + 31483093 = 31483250
163 + 31483087 = 31483250
181 + 31483069 = 31483250
199 + 31483051 = 31483250
277 + 31482973 = 31483250
541 + 31482709 = 31483250

Showing the first eight; more decompositions exist.
