Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85788, here are decompositions:

7 + 85781 = 85788
37 + 85751 = 85788
71 + 85717 = 85788
97 + 85691 = 85788
127 + 85661 = 85788
149 + 85639 = 85788
167 + 85621 = 85788
181 + 85607 = 85788

Showing the first eight; more decompositions exist.
