Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624678, here are decompositions:
- 5 + 31624673 = 31624678
- 17 + 31624661 = 31624678
- 47 + 31624631 = 31624678
- 131 + 31624547 = 31624678
- 167 + 31624511 = 31624678
- 311 + 31624367 = 31624678
- 347 + 31624331 = 31624678
- 401 + 31624277 = 31624678
Showing the first eight; more decompositions exist.
