Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31132, here are decompositions:
- 11 + 31121 = 31132
- 41 + 31091 = 31132
- 53 + 31079 = 31132
- 113 + 31019 = 31132
- 149 + 30983 = 31132
- 191 + 30941 = 31132
- 239 + 30893 = 31132
- 251 + 30881 = 31132
Showing the first eight; more decompositions exist.
