Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71582, here are decompositions:

13 + 71569 = 71582
19 + 71563 = 71582
31 + 71551 = 71582
79 + 71503 = 71582
103 + 71479 = 71582
109 + 71473 = 71582
139 + 71443 = 71582
163 + 71419 = 71582

Showing the first eight; more decompositions exist.
