Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47220, here are decompositions:
- 13 + 47207 = 47220
- 31 + 47189 = 47220
- 59 + 47161 = 47220
- 71 + 47149 = 47220
- 73 + 47147 = 47220
- 83 + 47137 = 47220
- 97 + 47123 = 47220
- 101 + 47119 = 47220
Showing the first eight; more decompositions exist.
