Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82870, here are decompositions:
- 23 + 82847 = 82870
- 59 + 82811 = 82870
- 71 + 82799 = 82870
- 83 + 82787 = 82870
- 89 + 82781 = 82870
- 107 + 82763 = 82870
- 113 + 82757 = 82870
- 149 + 82721 = 82870
Showing the first eight; more decompositions exist.
