Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126998, here are decompositions:
- 31 + 126967 = 126998
- 37 + 126961 = 126998
- 139 + 126859 = 126998
- 241 + 126757 = 126998
- 307 + 126691 = 126998
- 367 + 126631 = 126998
- 397 + 126601 = 126998
- 457 + 126541 = 126998
Showing the first eight; more decompositions exist.
