Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68986, here are decompositions:

23 + 68963 = 68986
59 + 68927 = 68986
83 + 68903 = 68986
89 + 68897 = 68986
107 + 68879 = 68986
167 + 68819 = 68986
173 + 68813 = 68986
257 + 68729 = 68986

Showing the first eight; more decompositions exist.
