Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47216, here are decompositions:
- 67 + 47149 = 47216
- 73 + 47143 = 47216
- 79 + 47137 = 47216
- 97 + 47119 = 47216
- 157 + 47059 = 47216
- 199 + 47017 = 47216
- 223 + 46993 = 47216
- 283 + 46933 = 47216
Showing the first eight; more decompositions exist.
