Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43970, here are decompositions:
- 7 + 43963 = 43970
- 19 + 43951 = 43970
- 37 + 43933 = 43970
- 79 + 43891 = 43970
- 103 + 43867 = 43970
- 181 + 43789 = 43970
- 193 + 43777 = 43970
- 211 + 43759 = 43970
Showing the first eight; more decompositions exist.
