Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20120, here are decompositions:
- 3 + 20117 = 20120
- 7 + 20113 = 20120
- 13 + 20107 = 20120
- 19 + 20101 = 20120
- 31 + 20089 = 20120
- 73 + 20047 = 20120
- 97 + 20023 = 20120
- 109 + 20011 = 20120
Showing the first eight; more decompositions exist.
