Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42942, here are decompositions:

5 + 42937 = 42942
13 + 42929 = 42942
19 + 42923 = 42942
41 + 42901 = 42942
43 + 42899 = 42942
79 + 42863 = 42942
83 + 42859 = 42942
89 + 42853 = 42942

Showing the first eight; more decompositions exist.
