Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589166, here are decompositions:

29 + 31589137 = 31589166
47 + 31589119 = 31589166
67 + 31589099 = 31589166
79 + 31589087 = 31589166
97 + 31589069 = 31589166
109 + 31589057 = 31589166
139 + 31589027 = 31589166
149 + 31589017 = 31589166

Showing the first eight; more decompositions exist.
