Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8018, here are decompositions:
- 7 + 8011 = 8018
- 67 + 7951 = 8018
- 139 + 7879 = 8018
- 151 + 7867 = 8018
- 229 + 7789 = 8018
- 277 + 7741 = 8018
- 331 + 7687 = 8018
- 337 + 7681 = 8018
Showing the first eight; more decompositions exist.
