Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47938, here are decompositions:
- 5 + 47933 = 47938
- 101 + 47837 = 47938
- 131 + 47807 = 47938
- 197 + 47741 = 47938
- 227 + 47711 = 47938
- 239 + 47699 = 47938
- 257 + 47681 = 47938
- 281 + 47657 = 47938
Showing the first eight; more decompositions exist.
