Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142980, here are decompositions:

7 + 142973 = 142980
11 + 142969 = 142980
17 + 142963 = 142980
31 + 142949 = 142980
41 + 142939 = 142980
73 + 142907 = 142980
83 + 142897 = 142980
107 + 142873 = 142980

Showing the first eight; more decompositions exist.
