Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83680, here are decompositions:
- 17 + 83663 = 83680
- 41 + 83639 = 83680
- 59 + 83621 = 83680
- 71 + 83609 = 83680
- 83 + 83597 = 83680
- 89 + 83591 = 83680
- 101 + 83579 = 83680
- 257 + 83423 = 83680
Showing the first eight; more decompositions exist.
