Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47208, here are decompositions:
- 19 + 47189 = 47208
- 47 + 47161 = 47208
- 59 + 47149 = 47208
- 61 + 47147 = 47208
- 71 + 47137 = 47208
- 79 + 47129 = 47208
- 89 + 47119 = 47208
- 97 + 47111 = 47208
Showing the first eight; more decompositions exist.
