Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71552, here are decompositions:

3 + 71549 = 71552
73 + 71479 = 71552
79 + 71473 = 71552
109 + 71443 = 71552
139 + 71413 = 71552
163 + 71389 = 71552
193 + 71359 = 71552
199 + 71353 = 71552

Showing the first eight; more decompositions exist.
