Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18244, here are decompositions:
- 11 + 18233 = 18244
- 53 + 18191 = 18244
- 101 + 18143 = 18244
- 113 + 18131 = 18244
- 167 + 18077 = 18244
- 197 + 18047 = 18244
- 257 + 17987 = 18244
- 263 + 17981 = 18244
Showing the first eight; more decompositions exist.
