Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31264, here are decompositions:
- 5 + 31259 = 31264
- 11 + 31253 = 31264
- 17 + 31247 = 31264
- 41 + 31223 = 31264
- 71 + 31193 = 31264
- 83 + 31181 = 31264
- 113 + 31151 = 31264
- 173 + 31091 = 31264
Showing the first eight; more decompositions exist.
