Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589832, here are decompositions:

5 + 31589827 = 31589832
13 + 31589819 = 31589832
59 + 31589773 = 31589832
61 + 31589771 = 31589832
73 + 31589759 = 31589832
101 + 31589731 = 31589832
139 + 31589693 = 31589832
149 + 31589683 = 31589832

Showing the first eight; more decompositions exist.
