Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82842, here are decompositions:
- 5 + 82837 = 82842
- 29 + 82813 = 82842
- 31 + 82811 = 82842
- 43 + 82799 = 82842
- 61 + 82781 = 82842
- 79 + 82763 = 82842
- 83 + 82759 = 82842
- 113 + 82729 = 82842
Showing the first eight; more decompositions exist.
