Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589106, here are decompositions:

7 + 31589099 = 31589106
19 + 31589087 = 31589106
37 + 31589069 = 31589106
79 + 31589027 = 31589106
89 + 31589017 = 31589106
113 + 31588993 = 31589106
127 + 31588979 = 31589106
149 + 31588957 = 31589106

Showing the first eight; more decompositions exist.
