Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20112, here are decompositions:
- 5 + 20107 = 20112
- 11 + 20101 = 20112
- 23 + 20089 = 20112
- 41 + 20071 = 20112
- 61 + 20051 = 20112
- 83 + 20029 = 20112
- 89 + 20023 = 20112
- 101 + 20011 = 20112
Showing the first eight; more decompositions exist.
