Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55558, here are decompositions:
- 11 + 55547 = 55558
- 17 + 55541 = 55558
- 29 + 55529 = 55558
- 47 + 55511 = 55558
- 71 + 55487 = 55558
- 89 + 55469 = 55558
- 101 + 55457 = 55558
- 227 + 55331 = 55558
Showing the first eight; more decompositions exist.
