Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589250, here are decompositions:

53 + 31589197 = 31589250
67 + 31589183 = 31589250
83 + 31589167 = 31589250
113 + 31589137 = 31589250
131 + 31589119 = 31589250
151 + 31589099 = 31589250
163 + 31589087 = 31589250
181 + 31589069 = 31589250

Showing the first eight; more decompositions exist.
