Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108980, here are decompositions:

13 + 108967 = 108980
19 + 108961 = 108980
31 + 108949 = 108980
37 + 108943 = 108980
73 + 108907 = 108980
97 + 108883 = 108980
103 + 108877 = 108980
181 + 108799 = 108980

Showing the first eight; more decompositions exist.
