Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51980, here are decompositions:

3 + 51977 = 51980
7 + 51973 = 51980
31 + 51949 = 51980
67 + 51913 = 51980
73 + 51907 = 51980
109 + 51871 = 51980
127 + 51853 = 51980
151 + 51829 = 51980

Showing the first eight; more decompositions exist.
