Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56440, here are decompositions:
- 3 + 56437 = 56440
- 23 + 56417 = 56440
- 47 + 56393 = 56440
- 71 + 56369 = 56440
- 107 + 56333 = 56440
- 173 + 56267 = 56440
- 191 + 56249 = 56440
- 233 + 56207 = 56440
Showing the first eight; more decompositions exist.
