Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20082, here are decompositions:
- 11 + 20071 = 20082
- 19 + 20063 = 20082
- 31 + 20051 = 20082
- 53 + 20029 = 20082
- 59 + 20023 = 20082
- 61 + 20021 = 20082
- 71 + 20011 = 20082
- 89 + 19993 = 20082
Showing the first eight; more decompositions exist.
