Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68580, here are decompositions:

13 + 68567 = 68580
37 + 68543 = 68580
41 + 68539 = 68580
59 + 68521 = 68580
73 + 68507 = 68580
79 + 68501 = 68580
89 + 68491 = 68580
97 + 68483 = 68580

Showing the first eight; more decompositions exist.
