Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71210, here are decompositions:
- 19 + 71191 = 71210
- 43 + 71167 = 71210
- 67 + 71143 = 71210
- 151 + 71059 = 71210
- 199 + 71011 = 71210
- 211 + 70999 = 71210
- 229 + 70981 = 71210
- 241 + 70969 = 71210
Showing the first eight; more decompositions exist.
