Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71018, here are decompositions:

7 + 71011 = 71018
19 + 70999 = 71018
37 + 70981 = 71018
61 + 70957 = 71018
67 + 70951 = 71018
97 + 70921 = 71018
127 + 70891 = 71018
139 + 70879 = 71018

Showing the first eight; more decompositions exist.
