Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71658, here are decompositions:

11 + 71647 = 71658
61 + 71597 = 71658
89 + 71569 = 71658
107 + 71551 = 71658
109 + 71549 = 71658
131 + 71527 = 71658
179 + 71479 = 71658
229 + 71429 = 71658

Showing the first eight; more decompositions exist.
