Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029820, here are decompositions:
- 17 + 1029803 = 1029820
- 53 + 1029767 = 1029820
- 89 + 1029731 = 1029820
- 131 + 1029689 = 1029820
- 167 + 1029653 = 1029820
- 173 + 1029647 = 1029820
- 227 + 1029593 = 1029820
- 251 + 1029569 = 1029820
Showing the first eight; more decompositions exist.
