Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613968, here are decompositions:
- 5 + 31613963 = 31613968
- 41 + 31613927 = 31613968
- 101 + 31613867 = 31613968
- 107 + 31613861 = 31613968
- 149 + 31613819 = 31613968
- 167 + 31613801 = 31613968
- 251 + 31613717 = 31613968
- 389 + 31613579 = 31613968
Showing the first eight; more decompositions exist.
