Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45942, here are decompositions:
- 73 + 45869 = 45942
- 79 + 45863 = 45942
- 89 + 45853 = 45942
- 101 + 45841 = 45942
- 109 + 45833 = 45942
- 163 + 45779 = 45942
- 179 + 45763 = 45942
- 191 + 45751 = 45942
Showing the first eight; more decompositions exist.
