Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71532, here are decompositions:

5 + 71527 = 71532
29 + 71503 = 71532
53 + 71479 = 71532
59 + 71473 = 71532
61 + 71471 = 71532
79 + 71453 = 71532
89 + 71443 = 71532
103 + 71429 = 71532

Showing the first eight; more decompositions exist.
