Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021718, here are decompositions:
- 7 + 1021711 = 1021718
- 67 + 1021651 = 1021718
- 97 + 1021621 = 1021718
- 157 + 1021561 = 1021718
- 277 + 1021441 = 1021718
- 331 + 1021387 = 1021718
- 337 + 1021381 = 1021718
- 349 + 1021369 = 1021718
Showing the first eight; more decompositions exist.
