Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68940, here are decompositions:

13 + 68927 = 68940
23 + 68917 = 68940
31 + 68909 = 68940
37 + 68903 = 68940
41 + 68899 = 68940
43 + 68897 = 68940
59 + 68881 = 68940
61 + 68879 = 68940

Showing the first eight; more decompositions exist.
