Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71542, here are decompositions:

5 + 71537 = 71542
59 + 71483 = 71542
71 + 71471 = 71542
89 + 71453 = 71542
113 + 71429 = 71542
131 + 71411 = 71542
179 + 71363 = 71542
281 + 71261 = 71542

Showing the first eight; more decompositions exist.
