Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18608, here are decompositions:
- 67 + 18541 = 18608
- 127 + 18481 = 18608
- 151 + 18457 = 18608
- 157 + 18451 = 18608
- 181 + 18427 = 18608
- 211 + 18397 = 18608
- 229 + 18379 = 18608
- 241 + 18367 = 18608
Showing the first eight; more decompositions exist.
