Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12898, here are decompositions:
- 5 + 12893 = 12898
- 89 + 12809 = 12898
- 107 + 12791 = 12898
- 227 + 12671 = 12898
- 239 + 12659 = 12898
- 251 + 12647 = 12898
- 257 + 12641 = 12898
- 359 + 12539 = 12898
Showing the first eight; more decompositions exist.
