Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19162, here are decompositions:

5 + 19157 = 19162
23 + 19139 = 19162
41 + 19121 = 19162
83 + 19079 = 19162
89 + 19073 = 19162
131 + 19031 = 19162
149 + 19013 = 19162
251 + 18911 = 19162

Showing the first eight; more decompositions exist.
