Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029870, here are decompositions:
- 11 + 1029859 = 1029870
- 29 + 1029841 = 1029870
- 31 + 1029839 = 1029870
- 43 + 1029827 = 1029870
- 47 + 1029823 = 1029870
- 67 + 1029803 = 1029870
- 103 + 1029767 = 1029870
- 113 + 1029757 = 1029870
Showing the first eight; more decompositions exist.
