Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51988, here are decompositions:
- 11 + 51977 = 51988
- 17 + 51971 = 51988
- 47 + 51941 = 51988
- 59 + 51929 = 51988
- 89 + 51899 = 51988
- 149 + 51839 = 51988
- 191 + 51797 = 51988
- 239 + 51749 = 51988
Showing the first eight; more decompositions exist.
