Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83818, here are decompositions:
- 5 + 83813 = 83818
- 41 + 83777 = 83818
- 101 + 83717 = 83818
- 179 + 83639 = 83818
- 197 + 83621 = 83818
- 227 + 83591 = 83818
- 239 + 83579 = 83818
- 257 + 83561 = 83818
Showing the first eight; more decompositions exist.
