Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146668, here are decompositions:
- 29 + 146639 = 146668
- 59 + 146609 = 146668
- 149 + 146519 = 146668
- 191 + 146477 = 146668
- 251 + 146417 = 146668
- 359 + 146309 = 146668
- 419 + 146249 = 146668
- 569 + 146099 = 146668
Showing the first eight; more decompositions exist.
