Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67312, here are decompositions:
- 5 + 67307 = 67312
- 23 + 67289 = 67312
- 41 + 67271 = 67312
- 101 + 67211 = 67312
- 131 + 67181 = 67312
- 173 + 67139 = 67312
- 191 + 67121 = 67312
- 233 + 67079 = 67312
Showing the first eight; more decompositions exist.
