Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19242, here are decompositions:

5 + 19237 = 19242
11 + 19231 = 19242
23 + 19219 = 19242
29 + 19213 = 19242
31 + 19211 = 19242
59 + 19183 = 19242
61 + 19181 = 19242
79 + 19163 = 19242

Showing the first eight; more decompositions exist.
