Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7018, here are decompositions:
- 5 + 7013 = 7018
- 17 + 7001 = 7018
- 41 + 6977 = 7018
- 47 + 6971 = 7018
- 59 + 6959 = 7018
- 71 + 6947 = 7018
- 101 + 6917 = 7018
- 107 + 6911 = 7018
Showing the first eight; more decompositions exist.
