Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008870, here are decompositions:
- 7 + 1008863 = 1008870
- 11 + 1008859 = 1008870
- 13 + 1008857 = 1008870
- 17 + 1008853 = 1008870
- 19 + 1008851 = 1008870
- 41 + 1008829 = 1008870
- 53 + 1008817 = 1008870
- 61 + 1008809 = 1008870
Showing the first eight; more decompositions exist.
