Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18070, here are decompositions:
- 11 + 18059 = 18070
- 23 + 18047 = 18070
- 29 + 18041 = 18070
- 83 + 17987 = 18070
- 89 + 17981 = 18070
- 113 + 17957 = 18070
- 131 + 17939 = 18070
- 149 + 17921 = 18070
Showing the first eight; more decompositions exist.
