Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589992, here are decompositions:

11 + 31589981 = 31589992
101 + 31589891 = 31589992
131 + 31589861 = 31589992
149 + 31589843 = 31589992
173 + 31589819 = 31589992
233 + 31589759 = 31589992
281 + 31589711 = 31589992
359 + 31589633 = 31589992

Showing the first eight; more decompositions exist.
