Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85668, here are decompositions:

7 + 85661 = 85668
29 + 85639 = 85668
41 + 85627 = 85668
47 + 85621 = 85668
61 + 85607 = 85668
67 + 85601 = 85668
71 + 85597 = 85668
97 + 85571 = 85668

Showing the first eight; more decompositions exist.
