Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47158, here are decompositions:
- 11 + 47147 = 47158
- 29 + 47129 = 47158
- 47 + 47111 = 47158
- 71 + 47087 = 47158
- 101 + 47057 = 47158
- 107 + 47051 = 47158
- 239 + 46919 = 47158
- 257 + 46901 = 47158
Showing the first eight; more decompositions exist.
