Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47180, here are decompositions:
- 19 + 47161 = 47180
- 31 + 47149 = 47180
- 37 + 47143 = 47180
- 43 + 47137 = 47180
- 61 + 47119 = 47180
- 139 + 47041 = 47180
- 163 + 47017 = 47180
- 223 + 46957 = 47180
Showing the first eight; more decompositions exist.
