Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71536, here are decompositions:

53 + 71483 = 71536
83 + 71453 = 71536
107 + 71429 = 71536
137 + 71399 = 71536
149 + 71387 = 71536
173 + 71363 = 71536
197 + 71339 = 71536
383 + 71153 = 71536

Showing the first eight; more decompositions exist.
