Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82638, here are decompositions:
- 5 + 82633 = 82638
- 19 + 82619 = 82638
- 29 + 82609 = 82638
- 37 + 82601 = 82638
- 47 + 82591 = 82638
- 67 + 82571 = 82638
- 71 + 82567 = 82638
- 79 + 82559 = 82638
Showing the first eight; more decompositions exist.
