Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71298, here are decompositions:

5 + 71293 = 71298
11 + 71287 = 71298
37 + 71261 = 71298
41 + 71257 = 71298
61 + 71237 = 71298
89 + 71209 = 71298
107 + 71191 = 71298
127 + 71171 = 71298

Showing the first eight; more decompositions exist.
