Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85740, here are decompositions:

7 + 85733 = 85740
23 + 85717 = 85740
29 + 85711 = 85740
37 + 85703 = 85740
71 + 85669 = 85740
73 + 85667 = 85740
79 + 85661 = 85740
97 + 85643 = 85740

Showing the first eight; more decompositions exist.
