Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468944, here are decompositions:
- 41 + 31468903 = 31468944
- 43 + 31468901 = 31468944
- 83 + 31468861 = 31468944
- 151 + 31468793 = 31468944
- 167 + 31468777 = 31468944
- 277 + 31468667 = 31468944
- 307 + 31468637 = 31468944
- 313 + 31468631 = 31468944
Showing the first eight; more decompositions exist.
