Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71588, here are decompositions:

19 + 71569 = 71588
37 + 71551 = 71588
61 + 71527 = 71588
109 + 71479 = 71588
151 + 71437 = 71588
199 + 71389 = 71588
229 + 71359 = 71588
241 + 71347 = 71588

Showing the first eight; more decompositions exist.
