Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57018, here are decompositions:
- 19 + 56999 = 57018
- 29 + 56989 = 57018
- 61 + 56957 = 57018
- 67 + 56951 = 57018
- 89 + 56929 = 57018
- 97 + 56921 = 57018
- 107 + 56911 = 57018
- 109 + 56909 = 57018
Showing the first eight; more decompositions exist.
