Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18010, here are decompositions:
- 23 + 17987 = 18010
- 29 + 17981 = 18010
- 53 + 17957 = 18010
- 71 + 17939 = 18010
- 89 + 17921 = 18010
- 101 + 17909 = 18010
- 107 + 17903 = 18010
- 173 + 17837 = 18010
Showing the first eight; more decompositions exist.
