Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18202, here are decompositions:
- 3 + 18199 = 18202
- 11 + 18191 = 18202
- 53 + 18149 = 18202
- 59 + 18143 = 18202
- 71 + 18131 = 18202
- 83 + 18119 = 18202
- 113 + 18089 = 18202
- 263 + 17939 = 18202
Showing the first eight; more decompositions exist.
