Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43880, here are decompositions:
- 13 + 43867 = 43880
- 79 + 43801 = 43880
- 97 + 43783 = 43880
- 103 + 43777 = 43880
- 127 + 43753 = 43880
- 163 + 43717 = 43880
- 211 + 43669 = 43880
- 229 + 43651 = 43880
Showing the first eight; more decompositions exist.
