Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1035840, here are decompositions:
- 11 + 1035829 = 1035840
- 59 + 1035781 = 1035840
- 79 + 1035761 = 1035840
- 97 + 1035743 = 1035840
- 107 + 1035733 = 1035840
- 181 + 1035659 = 1035840
- 191 + 1035649 = 1035840
- 199 + 1035641 = 1035840
Showing the first eight; more decompositions exist.
