Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589006, here are decompositions:

13 + 31588993 = 31589006
73 + 31588933 = 31589006
79 + 31588927 = 31589006
109 + 31588897 = 31589006
193 + 31588813 = 31589006
199 + 31588807 = 31589006
307 + 31588699 = 31589006
313 + 31588693 = 31589006

Showing the first eight; more decompositions exist.
