Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47188, here are decompositions:
- 41 + 47147 = 47188
- 59 + 47129 = 47188
- 101 + 47087 = 47188
- 131 + 47057 = 47188
- 137 + 47051 = 47188
- 191 + 46997 = 47188
- 269 + 46919 = 47188
- 311 + 46877 = 47188
Showing the first eight; more decompositions exist.
