Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31964, here are decompositions:
- 7 + 31957 = 31964
- 73 + 31891 = 31964
- 193 + 31771 = 31964
- 223 + 31741 = 31964
- 241 + 31723 = 31964
- 277 + 31687 = 31964
- 307 + 31657 = 31964
- 337 + 31627 = 31964
Showing the first eight; more decompositions exist.
