Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109980, here are decompositions:

19 + 109961 = 109980
37 + 109943 = 109980
43 + 109937 = 109980
61 + 109919 = 109980
67 + 109913 = 109980
83 + 109897 = 109980
89 + 109891 = 109980
97 + 109883 = 109980

Showing the first eight; more decompositions exist.
