Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589010, here are decompositions:

17 + 31588993 = 31589010
31 + 31588979 = 31589010
53 + 31588957 = 31589010
59 + 31588951 = 31589010
67 + 31588943 = 31589010
83 + 31588927 = 31589010
113 + 31588897 = 31589010
163 + 31588847 = 31589010

Showing the first eight; more decompositions exist.
