Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105980, here are decompositions:

3 + 105977 = 105980
13 + 105967 = 105980
37 + 105943 = 105980
67 + 105913 = 105980
73 + 105907 = 105980
97 + 105883 = 105980
109 + 105871 = 105980
151 + 105829 = 105980

Showing the first eight; more decompositions exist.
