Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71128, here are decompositions:

47 + 71081 = 71128
59 + 71069 = 71128
89 + 71039 = 71128
131 + 70997 = 71128
137 + 70991 = 71128
149 + 70979 = 71128
179 + 70949 = 71128
191 + 70937 = 71128

Showing the first eight; more decompositions exist.
