Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523510, here are decompositions:
- 37 + 31523473 = 31523510
- 43 + 31523467 = 31523510
- 103 + 31523407 = 31523510
- 163 + 31523347 = 31523510
- 181 + 31523329 = 31523510
- 283 + 31523227 = 31523510
- 349 + 31523161 = 31523510
- 367 + 31523143 = 31523510
Showing the first eight; more decompositions exist.
