Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42242, here are decompositions:

3 + 42239 = 42242
19 + 42223 = 42242
61 + 42181 = 42242
73 + 42169 = 42242
103 + 42139 = 42242
181 + 42061 = 42242
199 + 42043 = 42242
223 + 42019 = 42242

Showing the first eight; more decompositions exist.
