Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6998, here are decompositions:
- 7 + 6991 = 6998
- 31 + 6967 = 6998
- 37 + 6961 = 6998
- 127 + 6871 = 6998
- 157 + 6841 = 6998
- 307 + 6691 = 6998
- 337 + 6661 = 6998
- 379 + 6619 = 6998
Showing the first eight; more decompositions exist.
