Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56406, here are decompositions:
- 5 + 56401 = 56406
- 13 + 56393 = 56406
- 23 + 56383 = 56406
- 29 + 56377 = 56406
- 37 + 56369 = 56406
- 47 + 56359 = 56406
- 73 + 56333 = 56406
- 107 + 56299 = 56406
Showing the first eight; more decompositions exist.
