Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18822, here are decompositions:
- 19 + 18803 = 18822
- 29 + 18793 = 18822
- 73 + 18749 = 18822
- 79 + 18743 = 18822
- 103 + 18719 = 18822
- 109 + 18713 = 18822
- 131 + 18691 = 18822
- 151 + 18671 = 18822
Showing the first eight; more decompositions exist.
