Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19228, here are decompositions:

17 + 19211 = 19228
47 + 19181 = 19228
71 + 19157 = 19228
89 + 19139 = 19228
107 + 19121 = 19228
149 + 19079 = 19228
191 + 19037 = 19228
197 + 19031 = 19228

Showing the first eight; more decompositions exist.
