Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71782, here are decompositions:

5 + 71777 = 71782
41 + 71741 = 71782
71 + 71711 = 71782
83 + 71699 = 71782
89 + 71693 = 71782
149 + 71633 = 71782
233 + 71549 = 71782
311 + 71471 = 71782

Showing the first eight; more decompositions exist.
