Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589130, here are decompositions:

11 + 31589119 = 31589130
31 + 31589099 = 31589130
43 + 31589087 = 31589130
61 + 31589069 = 31589130
73 + 31589057 = 31589130
103 + 31589027 = 31589130
113 + 31589017 = 31589130
137 + 31588993 = 31589130

Showing the first eight; more decompositions exist.
