Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31112, here are decompositions:
- 31 + 31081 = 31112
- 43 + 31069 = 31112
- 61 + 31051 = 31112
- 73 + 31039 = 31112
- 79 + 31033 = 31112
- 163 + 30949 = 31112
- 181 + 30931 = 31112
- 241 + 30871 = 31112
Showing the first eight; more decompositions exist.
