Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71504, here are decompositions:

31 + 71473 = 71504
61 + 71443 = 71504
67 + 71437 = 71504
151 + 71353 = 71504
157 + 71347 = 71504
163 + 71341 = 71504
211 + 71293 = 71504
241 + 71263 = 71504

Showing the first eight; more decompositions exist.
