Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5648, here are decompositions:
- 7 + 5641 = 5648
- 67 + 5581 = 5648
- 79 + 5569 = 5648
- 127 + 5521 = 5648
- 199 + 5449 = 5648
- 211 + 5437 = 5648
- 229 + 5419 = 5648
- 241 + 5407 = 5648
Showing the first eight; more decompositions exist.
