Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31992, here are decompositions:
- 11 + 31981 = 31992
- 19 + 31973 = 31992
- 29 + 31963 = 31992
- 101 + 31891 = 31992
- 109 + 31883 = 31992
- 193 + 31799 = 31992
- 199 + 31793 = 31992
- 223 + 31769 = 31992
Showing the first eight; more decompositions exist.
