Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589046, here are decompositions:

19 + 31589027 = 31589046
29 + 31589017 = 31589046
53 + 31588993 = 31589046
67 + 31588979 = 31589046
89 + 31588957 = 31589046
103 + 31588943 = 31589046
113 + 31588933 = 31589046
149 + 31588897 = 31589046

Showing the first eight; more decompositions exist.
