Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 906, here are decompositions:
- 19 + 887 = 906
- 23 + 883 = 906
- 29 + 877 = 906
- 43 + 863 = 906
- 47 + 859 = 906
- 53 + 853 = 906
- 67 + 839 = 906
- 79 + 827 = 906
Showing the first eight; more decompositions exist.
