Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55556, here are decompositions:
- 157 + 55399 = 55556
- 223 + 55333 = 55556
- 307 + 55249 = 55556
- 313 + 55243 = 55556
- 337 + 55219 = 55556
- 349 + 55207 = 55556
- 409 + 55147 = 55556
- 439 + 55117 = 55556
Showing the first eight; more decompositions exist.
