Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71028, here are decompositions:

5 + 71023 = 71028
17 + 71011 = 71028
29 + 70999 = 71028
31 + 70997 = 71028
37 + 70991 = 71028
47 + 70981 = 71028
59 + 70969 = 71028
71 + 70957 = 71028

Showing the first eight; more decompositions exist.
