Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67212, here are decompositions:
- 23 + 67189 = 67212
- 31 + 67181 = 67212
- 43 + 67169 = 67212
- 59 + 67153 = 67212
- 71 + 67141 = 67212
- 73 + 67139 = 67212
- 83 + 67129 = 67212
- 109 + 67103 = 67212
Showing the first eight; more decompositions exist.
