Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13556, here are decompositions:
- 3 + 13553 = 13556
- 19 + 13537 = 13556
- 43 + 13513 = 13556
- 79 + 13477 = 13556
- 139 + 13417 = 13556
- 157 + 13399 = 13556
- 229 + 13327 = 13556
- 307 + 13249 = 13556
Showing the first eight; more decompositions exist.
