Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483828, here are decompositions:

29 + 31483799 = 31483828
137 + 31483691 = 31483828
179 + 31483649 = 31483828
251 + 31483577 = 31483828
281 + 31483547 = 31483828
359 + 31483469 = 31483828
521 + 31483307 = 31483828
599 + 31483229 = 31483828

Showing the first eight; more decompositions exist.
