Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47112, here are decompositions:
- 19 + 47093 = 47112
- 53 + 47059 = 47112
- 61 + 47051 = 47112
- 71 + 47041 = 47112
- 179 + 46933 = 47112
- 193 + 46919 = 47112
- 211 + 46901 = 47112
- 223 + 46889 = 47112
Showing the first eight; more decompositions exist.
