Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983840, here are decompositions:
- 31 + 983809 = 983840
- 37 + 983803 = 983840
- 103 + 983737 = 983840
- 139 + 983701 = 983840
- 181 + 983659 = 983840
- 223 + 983617 = 983840
- 283 + 983557 = 983840
- 307 + 983533 = 983840
Showing the first eight; more decompositions exist.
