Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42980, here are decompositions:

13 + 42967 = 42980
19 + 42961 = 42980
37 + 42943 = 42980
43 + 42937 = 42980
79 + 42901 = 42980
127 + 42853 = 42980
139 + 42841 = 42980
151 + 42829 = 42980

Showing the first eight; more decompositions exist.
