Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13148, here are decompositions:
- 139 + 13009 = 13148
- 181 + 12967 = 13148
- 229 + 12919 = 13148
- 241 + 12907 = 13148
- 307 + 12841 = 13148
- 349 + 12799 = 13148
- 367 + 12781 = 13148
- 409 + 12739 = 13148
Showing the first eight; more decompositions exist.
