Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85782, here are decompositions:

31 + 85751 = 85782
71 + 85711 = 85782
79 + 85703 = 85782
113 + 85669 = 85782
139 + 85643 = 85782
163 + 85619 = 85782
181 + 85601 = 85782
211 + 85571 = 85782

Showing the first eight; more decompositions exist.
