Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10878, here are decompositions:
- 11 + 10867 = 10878
- 17 + 10861 = 10878
- 19 + 10859 = 10878
- 31 + 10847 = 10878
- 41 + 10837 = 10878
- 47 + 10831 = 10878
- 79 + 10799 = 10878
- 89 + 10789 = 10878
Showing the first eight; more decompositions exist.
