Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19422, here are decompositions:

5 + 19417 = 19422
19 + 19403 = 19422
31 + 19391 = 19422
41 + 19381 = 19422
43 + 19379 = 19422
89 + 19333 = 19422
103 + 19319 = 19422
113 + 19309 = 19422

Showing the first eight; more decompositions exist.
