Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5556, here are decompositions:
- 29 + 5527 = 5556
- 37 + 5519 = 5556
- 53 + 5503 = 5556
- 73 + 5483 = 5556
- 79 + 5477 = 5556
- 107 + 5449 = 5556
- 113 + 5443 = 5556
- 137 + 5419 = 5556
Showing the first eight; more decompositions exist.
