Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71528, here are decompositions:

109 + 71419 = 71528
139 + 71389 = 71528
181 + 71347 = 71528
199 + 71329 = 71528
211 + 71317 = 71528
241 + 71287 = 71528
271 + 71257 = 71528
337 + 71191 = 71528

Showing the first eight; more decompositions exist.
