Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55018, here are decompositions:
- 17 + 55001 = 55018
- 59 + 54959 = 55018
- 101 + 54917 = 55018
- 137 + 54881 = 55018
- 149 + 54869 = 55018
- 167 + 54851 = 55018
- 239 + 54779 = 55018
- 251 + 54767 = 55018
Showing the first eight; more decompositions exist.
