Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589848, here are decompositions:

5 + 31589843 = 31589848
29 + 31589819 = 31589848
71 + 31589777 = 31589848
89 + 31589759 = 31589848
137 + 31589711 = 31589848
281 + 31589567 = 31589848
509 + 31589339 = 31589848
557 + 31589291 = 31589848

Showing the first eight; more decompositions exist.
