Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47944, here are decompositions:
- 5 + 47939 = 47944
- 11 + 47933 = 47944
- 41 + 47903 = 47944
- 101 + 47843 = 47944
- 107 + 47837 = 47944
- 137 + 47807 = 47944
- 167 + 47777 = 47944
- 227 + 47717 = 47944
Showing the first eight; more decompositions exist.
