Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61828, here are decompositions:
- 47 + 61781 = 61828
- 71 + 61757 = 61828
- 191 + 61637 = 61828
- 197 + 61631 = 61828
- 269 + 61559 = 61828
- 281 + 61547 = 61828
- 317 + 61511 = 61828
- 359 + 61469 = 61828
Showing the first eight; more decompositions exist.
