Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1035720, here are decompositions:
- 13 + 1035707 = 1035720
- 61 + 1035659 = 1035720
- 71 + 1035649 = 1035720
- 79 + 1035641 = 1035720
- 83 + 1035637 = 1035720
- 89 + 1035631 = 1035720
- 107 + 1035613 = 1035720
- 113 + 1035607 = 1035720
Showing the first eight; more decompositions exist.
