Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138848, here are decompositions:
- 7 + 138841 = 138848
- 19 + 138829 = 138848
- 109 + 138739 = 138848
- 211 + 138637 = 138848
- 271 + 138577 = 138848
- 277 + 138571 = 138848
- 331 + 138517 = 138848
- 337 + 138511 = 138848
Showing the first eight; more decompositions exist.
