Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68920, here are decompositions:

3 + 68917 = 68920
11 + 68909 = 68920
17 + 68903 = 68920
23 + 68897 = 68920
29 + 68891 = 68920
41 + 68879 = 68920
101 + 68819 = 68920
107 + 68813 = 68920

Showing the first eight; more decompositions exist.
