Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523232, here are decompositions:
- 5 + 31523227 = 31523232
- 11 + 31523221 = 31523232
- 23 + 31523209 = 31523232
- 31 + 31523201 = 31523232
- 71 + 31523161 = 31523232
- 89 + 31523143 = 31523232
- 101 + 31523131 = 31523232
- 113 + 31523119 = 31523232
Showing the first eight; more decompositions exist.
