Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83212, here are decompositions:
- 5 + 83207 = 83212
- 149 + 83063 = 83212
- 401 + 82811 = 83212
- 419 + 82793 = 83212
- 431 + 82781 = 83212
- 449 + 82763 = 83212
- 491 + 82721 = 83212
- 593 + 82619 = 83212
Showing the first eight; more decompositions exist.
