Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68646, here are decompositions:
- 7 + 68639 = 68646
- 13 + 68633 = 68646
- 79 + 68567 = 68646
- 103 + 68543 = 68646
- 107 + 68539 = 68646
- 139 + 68507 = 68646
- 157 + 68489 = 68646
- 163 + 68483 = 68646
Showing the first eight; more decompositions exist.
