Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43242, here are decompositions:
- 5 + 43237 = 43242
- 19 + 43223 = 43242
- 41 + 43201 = 43242
- 53 + 43189 = 43242
- 83 + 43159 = 43242
- 109 + 43133 = 43242
- 139 + 43103 = 43242
- 149 + 43093 = 43242
Showing the first eight; more decompositions exist.
