Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67638, here are decompositions:
- 7 + 67631 = 67638
- 19 + 67619 = 67638
- 31 + 67607 = 67638
- 37 + 67601 = 67638
- 59 + 67579 = 67638
- 61 + 67577 = 67638
- 71 + 67567 = 67638
- 79 + 67559 = 67638
Showing the first eight; more decompositions exist.
