Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577720, here are decompositions:
- 53 + 577667 = 577720
- 83 + 577637 = 577720
- 107 + 577613 = 577720
- 131 + 577589 = 577720
- 173 + 577547 = 577720
- 191 + 577529 = 577720
- 197 + 577523 = 577720
- 257 + 577463 = 577720
Showing the first eight; more decompositions exist.
