Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38980, here are decompositions:

3 + 38977 = 38980
47 + 38933 = 38980
59 + 38921 = 38980
89 + 38891 = 38980
107 + 38873 = 38980
113 + 38867 = 38980
197 + 38783 = 38980
233 + 38747 = 38980

Showing the first eight; more decompositions exist.
