Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27018, here are decompositions:
- 7 + 27011 = 27018
- 31 + 26987 = 27018
- 37 + 26981 = 27018
- 59 + 26959 = 27018
- 67 + 26951 = 27018
- 71 + 26947 = 27018
- 97 + 26921 = 27018
- 127 + 26891 = 27018
Showing the first eight; more decompositions exist.
