Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 896, here are decompositions:
- 13 + 883 = 896
- 19 + 877 = 896
- 37 + 859 = 896
- 43 + 853 = 896
- 67 + 829 = 896
- 73 + 823 = 896
- 109 + 787 = 896
- 127 + 769 = 896
Showing the first eight; more decompositions exist.
