Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67210, here are decompositions:
- 23 + 67187 = 67210
- 29 + 67181 = 67210
- 41 + 67169 = 67210
- 53 + 67157 = 67210
- 71 + 67139 = 67210
- 89 + 67121 = 67210
- 107 + 67103 = 67210
- 131 + 67079 = 67210
Showing the first eight; more decompositions exist.
