Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589000, here are decompositions:

7 + 31588993 = 31589000
43 + 31588957 = 31589000
67 + 31588933 = 31589000
73 + 31588927 = 31589000
103 + 31588897 = 31589000
193 + 31588807 = 31589000
307 + 31588693 = 31589000
397 + 31588603 = 31589000

Showing the first eight; more decompositions exist.
