Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146686, here are decompositions:
- 3 + 146683 = 146686
- 5 + 146681 = 146686
- 17 + 146669 = 146686
- 47 + 146639 = 146686
- 83 + 146603 = 146686
- 167 + 146519 = 146686
- 173 + 146513 = 146686
- 263 + 146423 = 146686
Showing the first eight; more decompositions exist.
