Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146724, here are decompositions:
- 5 + 146719 = 146724
- 23 + 146701 = 146724
- 41 + 146683 = 146724
- 43 + 146681 = 146724
- 47 + 146677 = 146724
- 107 + 146617 = 146724
- 181 + 146543 = 146724
- 197 + 146527 = 146724
Showing the first eight; more decompositions exist.
