Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19122, here are decompositions:

41 + 19081 = 19122
43 + 19079 = 19122
53 + 19069 = 19122
71 + 19051 = 19122
109 + 19013 = 19122
113 + 19009 = 19122
149 + 18973 = 19122
163 + 18959 = 19122

Showing the first eight; more decompositions exist.
