Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159842, here are decompositions:
- 3 + 159839 = 159842
- 31 + 159811 = 159842
- 43 + 159799 = 159842
- 73 + 159769 = 159842
- 79 + 159763 = 159842
- 103 + 159739 = 159842
- 211 + 159631 = 159842
- 271 + 159571 = 159842
Showing the first eight; more decompositions exist.
