Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51998, here are decompositions:
- 7 + 51991 = 51998
- 127 + 51871 = 51998
- 139 + 51859 = 51998
- 181 + 51817 = 51998
- 211 + 51787 = 51998
- 229 + 51769 = 51998
- 277 + 51721 = 51998
- 307 + 51691 = 51998
Showing the first eight; more decompositions exist.
