Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474944, here are decompositions:
- 13 + 31474931 = 31474944
- 71 + 31474873 = 31474944
- 167 + 31474777 = 31474944
- 181 + 31474763 = 31474944
- 197 + 31474747 = 31474944
- 211 + 31474733 = 31474944
- 223 + 31474721 = 31474944
- 251 + 31474693 = 31474944
Showing the first eight; more decompositions exist.
