Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42216, here are decompositions:

7 + 42209 = 42216
19 + 42197 = 42216
23 + 42193 = 42216
29 + 42187 = 42216
37 + 42179 = 42216
47 + 42169 = 42216
59 + 42157 = 42216
127 + 42089 = 42216

Showing the first eight; more decompositions exist.
