Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168426, here are decompositions:
- 17 + 168409 = 168426
- 73 + 168353 = 168426
- 79 + 168347 = 168426
- 103 + 168323 = 168426
- 149 + 168277 = 168426
- 157 + 168269 = 168426
- 163 + 168263 = 168426
- 173 + 168253 = 168426
Showing the first eight; more decompositions exist.
