Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038870, here are decompositions:
- 37 + 1038833 = 1038870
- 43 + 1038827 = 1038870
- 47 + 1038823 = 1038870
- 59 + 1038811 = 1038870
- 67 + 1038803 = 1038870
- 73 + 1038797 = 1038870
- 113 + 1038757 = 1038870
- 139 + 1038731 = 1038870
Showing the first eight; more decompositions exist.
