Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9802, here are decompositions:
- 11 + 9791 = 9802
- 53 + 9749 = 9802
- 59 + 9743 = 9802
- 83 + 9719 = 9802
- 113 + 9689 = 9802
- 173 + 9629 = 9802
- 179 + 9623 = 9802
- 251 + 9551 = 9802
Showing the first eight; more decompositions exist.
