Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71120, here are decompositions:

31 + 71089 = 71120
61 + 71059 = 71120
97 + 71023 = 71120
109 + 71011 = 71120
139 + 70981 = 71120
151 + 70969 = 71120
163 + 70957 = 71120
199 + 70921 = 71120

Showing the first eight; more decompositions exist.
