Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15162, here are decompositions:
- 13 + 15149 = 15162
- 23 + 15139 = 15162
- 31 + 15131 = 15162
- 41 + 15121 = 15162
- 61 + 15101 = 15162
- 71 + 15091 = 15162
- 79 + 15083 = 15162
- 89 + 15073 = 15162
Showing the first eight; more decompositions exist.
