Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43938, here are decompositions:
- 5 + 43933 = 43938
- 47 + 43891 = 43938
- 71 + 43867 = 43938
- 137 + 43801 = 43938
- 149 + 43789 = 43938
- 151 + 43787 = 43938
- 157 + 43781 = 43938
- 179 + 43759 = 43938
Showing the first eight; more decompositions exist.
