Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26980, here are decompositions:

29 + 26951 = 26980
53 + 26927 = 26980
59 + 26921 = 26980
89 + 26891 = 26980
101 + 26879 = 26980
131 + 26849 = 26980
167 + 26813 = 26980
179 + 26801 = 26980

Showing the first eight; more decompositions exist.
