Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71180, here are decompositions:

13 + 71167 = 71180
19 + 71161 = 71180
37 + 71143 = 71180
61 + 71119 = 71180
157 + 71023 = 71180
181 + 70999 = 71180
199 + 70981 = 71180
211 + 70969 = 71180

Showing the first eight; more decompositions exist.
