Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83668, here are decompositions:
- 5 + 83663 = 83668
- 29 + 83639 = 83668
- 47 + 83621 = 83668
- 59 + 83609 = 83668
- 71 + 83597 = 83668
- 89 + 83579 = 83668
- 107 + 83561 = 83668
- 131 + 83537 = 83668
Showing the first eight; more decompositions exist.
