Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71824, here are decompositions:

3 + 71821 = 71824
17 + 71807 = 71824
47 + 71777 = 71824
83 + 71741 = 71824
113 + 71711 = 71824
131 + 71693 = 71824
191 + 71633 = 71824
227 + 71597 = 71824

Showing the first eight; more decompositions exist.
