Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71118, here are decompositions:

29 + 71089 = 71118
37 + 71081 = 71118
59 + 71059 = 71118
79 + 71039 = 71118
107 + 71011 = 71118
127 + 70991 = 71118
137 + 70981 = 71118
139 + 70979 = 71118

Showing the first eight; more decompositions exist.
