Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67712, here are decompositions:
- 3 + 67709 = 67712
- 13 + 67699 = 67712
- 61 + 67651 = 67712
- 181 + 67531 = 67712
- 223 + 67489 = 67712
- 283 + 67429 = 67712
- 313 + 67399 = 67712
- 373 + 67339 = 67712
Showing the first eight; more decompositions exist.
