Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83640, here are decompositions:
- 19 + 83621 = 83640
- 23 + 83617 = 83640
- 31 + 83609 = 83640
- 43 + 83597 = 83640
- 61 + 83579 = 83640
- 79 + 83561 = 83640
- 83 + 83557 = 83640
- 103 + 83537 = 83640
Showing the first eight; more decompositions exist.
