Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5456, here are decompositions:
- 7 + 5449 = 5456
- 13 + 5443 = 5456
- 19 + 5437 = 5456
- 37 + 5419 = 5456
- 43 + 5413 = 5456
- 109 + 5347 = 5456
- 223 + 5233 = 5456
- 229 + 5227 = 5456
Showing the first eight; more decompositions exist.
