Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43994, here are decompositions:
- 3 + 43991 = 43994
- 7 + 43987 = 43994
- 31 + 43963 = 43994
- 43 + 43951 = 43994
- 61 + 43933 = 43994
- 103 + 43891 = 43994
- 127 + 43867 = 43994
- 193 + 43801 = 43994
Showing the first eight; more decompositions exist.
