Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42226, here are decompositions:

3 + 42223 = 42226
5 + 42221 = 42226
17 + 42209 = 42226
29 + 42197 = 42226
47 + 42179 = 42226
137 + 42089 = 42226
227 + 41999 = 42226
257 + 41969 = 42226

Showing the first eight; more decompositions exist.
