Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523832, here are decompositions:
- 29 + 31523803 = 31523832
- 31 + 31523801 = 31523832
- 71 + 31523761 = 31523832
- 79 + 31523753 = 31523832
- 83 + 31523749 = 31523832
- 163 + 31523669 = 31523832
- 173 + 31523659 = 31523832
- 181 + 31523651 = 31523832
Showing the first eight; more decompositions exist.
