Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48638, here are decompositions:
- 19 + 48619 = 48638
- 67 + 48571 = 48638
- 97 + 48541 = 48638
- 151 + 48487 = 48638
- 157 + 48481 = 48638
- 229 + 48409 = 48638
- 241 + 48397 = 48638
- 367 + 48271 = 48638
Showing the first eight; more decompositions exist.
