Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71748, here are decompositions:

7 + 71741 = 71748
29 + 71719 = 71748
37 + 71711 = 71748
41 + 71707 = 71748
101 + 71647 = 71748
151 + 71597 = 71748
179 + 71569 = 71748
197 + 71551 = 71748

Showing the first eight; more decompositions exist.
