Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47894, here are decompositions:
- 13 + 47881 = 47894
- 37 + 47857 = 47894
- 97 + 47797 = 47894
- 103 + 47791 = 47894
- 151 + 47743 = 47894
- 157 + 47737 = 47894
- 181 + 47713 = 47894
- 193 + 47701 = 47894
Showing the first eight; more decompositions exist.
