Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80018, here are decompositions:
- 19 + 79999 = 80018
- 31 + 79987 = 80018
- 79 + 79939 = 80018
- 151 + 79867 = 80018
- 157 + 79861 = 80018
- 241 + 79777 = 80018
- 331 + 79687 = 80018
- 349 + 79669 = 80018
Showing the first eight; more decompositions exist.
