Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68980, here are decompositions:

17 + 68963 = 68980
53 + 68927 = 68980
71 + 68909 = 68980
83 + 68897 = 68980
89 + 68891 = 68980
101 + 68879 = 68980
167 + 68813 = 68980
251 + 68729 = 68980

Showing the first eight; more decompositions exist.
