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.
