Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523432, here are decompositions:
- 13 + 31523419 = 31523432
- 103 + 31523329 = 31523432
- 139 + 31523293 = 31523432
- 181 + 31523251 = 31523432
- 211 + 31523221 = 31523432
- 223 + 31523209 = 31523432
- 271 + 31523161 = 31523432
- 313 + 31523119 = 31523432
Showing the first eight; more decompositions exist.
