Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67722, here are decompositions:
- 13 + 67709 = 67722
- 23 + 67699 = 67722
- 43 + 67679 = 67722
- 71 + 67651 = 67722
- 103 + 67619 = 67722
- 163 + 67559 = 67722
- 191 + 67531 = 67722
- 199 + 67523 = 67722
Showing the first eight; more decompositions exist.
