Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 244, here are decompositions:

3 + 241 = 244
5 + 239 = 244
11 + 233 = 244
17 + 227 = 244
47 + 197 = 244
53 + 191 = 244
71 + 173 = 244
107 + 137 = 244

Showing the first eight; more decompositions exist.
