Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71248, here are decompositions:

11 + 71237 = 71248
101 + 71147 = 71248
167 + 71081 = 71248
179 + 71069 = 71248
251 + 70997 = 71248
257 + 70991 = 71248
269 + 70979 = 71248
311 + 70937 = 71248

Showing the first eight; more decompositions exist.
