Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68772, here are decompositions:
- 5 + 68767 = 68772
- 23 + 68749 = 68772
- 29 + 68743 = 68772
- 43 + 68729 = 68772
- 59 + 68713 = 68772
- 61 + 68711 = 68772
- 73 + 68699 = 68772
- 89 + 68683 = 68772
Showing the first eight; more decompositions exist.
