Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31148, here are decompositions:
- 67 + 31081 = 31148
- 79 + 31069 = 31148
- 97 + 31051 = 31148
- 109 + 31039 = 31148
- 199 + 30949 = 31148
- 211 + 30937 = 31148
- 277 + 30871 = 31148
- 307 + 30841 = 31148
Showing the first eight; more decompositions exist.
