Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486944, here are decompositions:
- 17 + 31486927 = 31486944
- 193 + 31486751 = 31486944
- 211 + 31486733 = 31486944
- 233 + 31486711 = 31486944
- 283 + 31486661 = 31486944
- 311 + 31486633 = 31486944
- 317 + 31486627 = 31486944
- 331 + 31486613 = 31486944
Showing the first eight; more decompositions exist.
