Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17142, here are decompositions:
- 5 + 17137 = 17142
- 19 + 17123 = 17142
- 43 + 17099 = 17142
- 89 + 17053 = 17142
- 101 + 17041 = 17142
- 109 + 17033 = 17142
- 113 + 17029 = 17142
- 131 + 17011 = 17142
Showing the first eight; more decompositions exist.
