Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984390, here are decompositions:
- 7 + 984383 = 984390
- 23 + 984367 = 984390
- 31 + 984359 = 984390
- 37 + 984353 = 984390
- 41 + 984349 = 984390
- 53 + 984337 = 984390
- 61 + 984329 = 984390
- 67 + 984323 = 984390
Showing the first eight; more decompositions exist.
