Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61648, here are decompositions:
- 5 + 61643 = 61648
- 11 + 61637 = 61648
- 17 + 61631 = 61648
- 89 + 61559 = 61648
- 101 + 61547 = 61648
- 137 + 61511 = 61648
- 179 + 61469 = 61648
- 239 + 61409 = 61648
Showing the first eight; more decompositions exist.
