Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47210, here are decompositions:
- 3 + 47207 = 47210
- 61 + 47149 = 47210
- 67 + 47143 = 47210
- 73 + 47137 = 47210
- 151 + 47059 = 47210
- 193 + 47017 = 47210
- 277 + 46933 = 47210
- 349 + 46861 = 47210
Showing the first eight; more decompositions exist.
