Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18758, here are decompositions:
- 67 + 18691 = 18758
- 79 + 18679 = 18758
- 97 + 18661 = 18758
- 241 + 18517 = 18758
- 277 + 18481 = 18758
- 307 + 18451 = 18758
- 331 + 18427 = 18758
- 379 + 18379 = 18758
Showing the first eight; more decompositions exist.
