Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61724, here are decompositions:
- 7 + 61717 = 61724
- 37 + 61687 = 61724
- 43 + 61681 = 61724
- 67 + 61657 = 61724
- 73 + 61651 = 61724
- 97 + 61627 = 61724
- 163 + 61561 = 61724
- 181 + 61543 = 61724
Showing the first eight; more decompositions exist.
