Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74878, here are decompositions:
- 5 + 74873 = 74878
- 17 + 74861 = 74878
- 47 + 74831 = 74878
- 107 + 74771 = 74878
- 131 + 74747 = 74878
- 149 + 74729 = 74878
- 179 + 74699 = 74878
- 191 + 74687 = 74878
Showing the first eight; more decompositions exist.
