Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47218, here are decompositions:
- 11 + 47207 = 47218
- 29 + 47189 = 47218
- 71 + 47147 = 47218
- 89 + 47129 = 47218
- 107 + 47111 = 47218
- 131 + 47087 = 47218
- 167 + 47051 = 47218
- 317 + 46901 = 47218
Showing the first eight; more decompositions exist.
