Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18548, here are decompositions:
- 7 + 18541 = 18548
- 31 + 18517 = 18548
- 67 + 18481 = 18548
- 97 + 18451 = 18548
- 109 + 18439 = 18548
- 151 + 18397 = 18548
- 181 + 18367 = 18548
- 241 + 18307 = 18548
Showing the first eight; more decompositions exist.
