Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18248, here are decompositions:
- 19 + 18229 = 18248
- 31 + 18217 = 18248
- 37 + 18211 = 18248
- 67 + 18181 = 18248
- 79 + 18169 = 18248
- 127 + 18121 = 18248
- 151 + 18097 = 18248
- 199 + 18049 = 18248
Showing the first eight; more decompositions exist.
