Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17138, here are decompositions:
- 31 + 17107 = 17138
- 61 + 17077 = 17138
- 97 + 17041 = 17138
- 109 + 17029 = 17138
- 127 + 17011 = 17138
- 151 + 16987 = 17138
- 157 + 16981 = 17138
- 211 + 16927 = 17138
Showing the first eight; more decompositions exist.
