Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39842, here are decompositions:
- 3 + 39839 = 39842
- 13 + 39829 = 39842
- 43 + 39799 = 39842
- 73 + 39769 = 39842
- 109 + 39733 = 39842
- 139 + 39703 = 39842
- 163 + 39679 = 39842
- 211 + 39631 = 39842
Showing the first eight; more decompositions exist.
