Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483948, here are decompositions:

29 + 31483919 = 31483948
59 + 31483889 = 31483948
71 + 31483877 = 31483948
107 + 31483841 = 31483948
149 + 31483799 = 31483948
257 + 31483691 = 31483948
401 + 31483547 = 31483948
479 + 31483469 = 31483948

Showing the first eight; more decompositions exist.
