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.
