Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42984, here are decompositions:

5 + 42979 = 42984
17 + 42967 = 42984
23 + 42961 = 42984
31 + 42953 = 42984
41 + 42943 = 42984
47 + 42937 = 42984
61 + 42923 = 42984
83 + 42901 = 42984

Showing the first eight; more decompositions exist.
