Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47878, here are decompositions:
- 41 + 47837 = 47878
- 59 + 47819 = 47878
- 71 + 47807 = 47878
- 101 + 47777 = 47878
- 137 + 47741 = 47878
- 167 + 47711 = 47878
- 179 + 47699 = 47878
- 197 + 47681 = 47878
Showing the first eight; more decompositions exist.
