Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71210, here are decompositions:

19 + 71191 = 71210
43 + 71167 = 71210
67 + 71143 = 71210
151 + 71059 = 71210
199 + 71011 = 71210
211 + 70999 = 71210
229 + 70981 = 71210
241 + 70969 = 71210

Showing the first eight; more decompositions exist.
