Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19222, here are decompositions:

3 + 19219 = 19222
11 + 19211 = 19222
41 + 19181 = 19222
59 + 19163 = 19222
83 + 19139 = 19222
101 + 19121 = 19222
149 + 19073 = 19222
191 + 19031 = 19222

Showing the first eight; more decompositions exist.
