Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589842, here are decompositions:

23 + 31589819 = 31589842
71 + 31589771 = 31589842
83 + 31589759 = 31589842
131 + 31589711 = 31589842
149 + 31589693 = 31589842
281 + 31589561 = 31589842
359 + 31589483 = 31589842
419 + 31589423 = 31589842

Showing the first eight; more decompositions exist.
