Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83890, here are decompositions:
- 17 + 83873 = 83890
- 47 + 83843 = 83890
- 113 + 83777 = 83890
- 173 + 83717 = 83890
- 227 + 83663 = 83890
- 251 + 83639 = 83890
- 269 + 83621 = 83890
- 281 + 83609 = 83890
Showing the first eight; more decompositions exist.
