Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43120, here are decompositions:
- 3 + 43117 = 43120
- 17 + 43103 = 43120
- 53 + 43067 = 43120
- 71 + 43049 = 43120
- 83 + 43037 = 43120
- 101 + 43019 = 43120
- 107 + 43013 = 43120
- 131 + 42989 = 43120
Showing the first eight; more decompositions exist.
