Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61864, here are decompositions:
- 3 + 61861 = 61864
- 83 + 61781 = 61864
- 107 + 61757 = 61864
- 113 + 61751 = 61864
- 191 + 61673 = 61864
- 197 + 61667 = 61864
- 227 + 61637 = 61864
- 233 + 61631 = 61864
Showing the first eight; more decompositions exist.
